"Mechanistic and Synthetic Aspects of Olefin Polymerizations Using
Ni(II) and Pd(II) Based Catalysts"
10:10 - 10:40 Coffee Break
Saturday Morning Session
Lash Miller Room
Session Chair: Ian Manners
10:40 - 11:00 EPR Study of the Reactions of the Polymerization Catalysts Cp*TiMe2E (E = Me, Cl, C6F5, OC6F5) with B(C6F5)3 and [Ph3C][B(C6F5)4]
Edan Williams and M. C. Baird
Department of Chemistry, Queen's University, Kingston (Ontario), Canada K7L 3N6.
The half sandwich titanium compounds of the type Cp*TiMe2E (Cp* = pentamethylcyclopentadienyl, E = Me, Cl, C6F5, OC6F5) have previously been shown to be efficient catalysts for the polymerization of a-olefins such as propylene and ethylene when activated with a suitable co-catalyst such as B(C6F5)3 or [PH3C][B(C6F5)4]. As well, under certain conditions, Cp*TiMe3 will polymerize styrene to produce syndiotactic polystyrene. It has been shown that under these conditions, a Ti3+ species is formed and these have been studied by EPR spectroscopy. We have studied the room temperature reactions of the above series of titanium compounds with both co-catalysts via EPR to determine under what conditions and to what extent these Ti3+ species are formed.
11:00 - 11:20 Desulfurization of Dibenzothiophene by a New Dinuclear Nickel Hydride Complex
David A. Vicic and William D. Jones
Department of Chemistry, University of Rochester, Rochester (New York), USA 14627-0216.
The new nickel hydride dimer [(dippe)NiH]2 (1) (dippe = 1,2-bis(di-i-propylphosphino)ethane) was found to react with various thiophenes at room temperature leading to the mono C,S-insertion complexes. The dibenzothiophene (DBT) adduct can further react with (dippe)Ni0 fragments producing novel organometallic compounds in which both of the C-S bonds of DBT have been cleaved. Reaction of the desulfurized species with hydrogen at room temperature leads to the production of biphenyl and the regeneration of 1. Reactivity of 1 with methyl substituted dibenzothiophenes will also be presented.
11:20 - 11:40 The Remarkable Complexity of the Reaction of Lowvalent Niobium with Amides
Maryam Tayebani and Sandro Gambarotta
Department of Chemistry, University of Ottawa, Ottawa (Ontario), Canada K1N 6N5
Reaction of the diamagnetic Nb(II) cluster, (TMEDA)2Nb2Cl5Li(TMEDA), with anionic organic amides forms different compounds depending on the nature of the amide organic substituents. A variety of transformations which have occurred including C-N bond cleavage, as well as formation of nitrides or complexes exhibiting unusual structures with exotic metal oxidation states will be presented and discussed.
11:40 - 12:00 Dehydrogenative Cross-Coupling of Primary Silanes and Phosphines - A reaction Catalyzed by Dimethyltitanocene
Ronghua Shu, Leijun Hao, Hee Gwon Woo, and John F. Harrod
Department of Chemistry, McGill University, Montreal (Quebec), Canada H3A 2K6
Dehydrogenative coupling between silanes and phosphines has been studied using dimethyltitanocene as the precatalyst. Triphosphatrisilacyclohexanes [(-SiHRPR'-)3, R = Ph or CH3Ph; R' = Cy or Ph] were afforded and characterized. The mechanism was proposed and discussed.
12:00 - 2:00 Lunch
Saturday Afternoon Session I
Lash Miller Room 158
Session Chair: Tony Poë
2:00 - 2:20 Singlet-Triplet Crossings in Nickel(II) Compounds, Studied by Polarized Absorption Spectroscopy
Guillaume Bussière and Christian Reber
Département de Chimie, Université de Montréal, Montréal (Québec), Canada H3C 3J7.
Nickel (II) compounds show electronic absorption spectra with unusual vibronic structure. Our goal is to rationalize this using the time-dependent theory of spectroscopy. Forbidden transitions to the singlet excited state (3A2g-> 1Eg, Oh) in all the studied compounds show high intensities and vibrational structure with high spacing. These observations can be explained by intersystem crossing betwen the singlet and a nearby triplet state (3T1g, Oh). The crossing dynamics are governed by the spin orbit coupling constant, l, wich can be obtained independently by RPE spectroscopy.
2:25 - 2:45 Ligand Electrochemical Parameters for Non-Innocent Ligands
Diego Venegas-Yazigi, A. B. P. Lever, Ramon O. Latorre, and Juan Costamagna
Chemistry Departments of York University, the University of Chile and the University of Santiago of Chile.
In 1990 electrochemical, or Lever, parameters were introduced to the literature [1]. With
these parameters it became possible to understand and predict the electrochemical behaviour of complexes with "innocent" ligands, i.e. ligands which do not exhibit redox activity. At the present stage it is important to study complexes with redox-active, "non-innocent" ligands, as is the case of quinones. Our group is now studying the series RuL2(BQDI), RuL(BQDI)2, Ru(BQDI)3 etc.where L is bipyridine [4], to extract an EL value for BQDI.
2:50 - 3:10 Effects of Vibronic Coupling in Cyanide Bridged Transition Metal Donor-Acceptor Complexes
J.F. Endicott, A. Macatangay, M.A. Watzky, X. Song, and S.E. Mazzetto.
Department of Chemistry, Wayne State University, Detroit (Michigan), USA 48202-3489.
Several properties of transition metal donors and acceptors have been found to be modified by D/A electronic coupling (HDA). Important among these is the CN- stretch which shifts to lower energy, when cyanide bridges D and A, in proportion to HDA2. The implicated interdependence of the bridging ligand nuclear coordinates and HDA implies that HDA is a function of the electron transfer coordinates and helps account for the observation that the Ru(II)/Ru(III) DACT absorption spectra are independent of M in Ru(II)-(BL)-Ru(III) complexes in which BL = LM(CN)2.
3:10 - 3:30 Coffee Break
Session Chair: Judith Poë
3:30 - 3:50 Structures and Magnetism of Copper(II) and Cobalt(II) Complexes with
Bis-2,4-pentadionato as a Bridging Ligand
You S. Zhang and Suning Wang
Department of Chemistry, Queen's University, Kingston (Ontario), Canada K7L 3N6.
The coordination chemistry of the bis(2,4-pentadionato) ligand with paramagnetic ions such as copper(II) and cobalt(II) has been investigated. The bis(2,4-pentadionato) ligand is believed to promote weak ferromagnetic interactions between two paramagnetic metal ions due to geometric constraint. Dinuclear cobalt(II) and copper(II) compounds containing the bis(2,4-pentadionato) and di-2-pyridylamine ligands have been obtained. A copper(II) polymer containing bis(2,4-pentadionato), di-2-pyridylamine and 4,4'-dipyridyl as ligands has been obtained too. The structures and magnetic properties of these compounds have been studied.
3:55 - 4:15 Novel Molecular Magnetic Materials
Christopher A. White, John E. Greedan, and Robert J. Crutchley
Department of Chemistry, Carleton University, Ottawa (Ontario), Canada K1S 5B6
The past several years have seen some great advancements in the synthesis of molecular magnetic materials and the goal of obtaining stable room temperature ferromagnetic materials seems within reach. An oligomeric copper complex was synthesized incoporating the 1,3-dicyanamidobenzene dianion (meta-dicyd2-) bridging ligand, namely [Cu(meta-dicyd)]n, which has demostrated spontaneous ferromagnetism at temperatures below 10 K. Our hypothesis is that the meta-dicyd2- bridging ligand will be an effective mediator of ferromagnetic exchange between two paramagnetic ions. When explored using theory, and supported by magnetic studies and a crystal structure of a model dinuclear system, [{(trpyCu}2-m-meta-dicyd]2+, the ferromagnetic directing properties of meta-dicyd2- should be elucidated.
4:20 - 4:40 Atoms in Molecules Theoretical Studies of Phosphorus Systems
Maggie A. Austen and Richard F. W. Bader
Department of Chemistry, McMaster University, Hamilton (Ontario), Canada L8S 4M1.
The topology of the electron density is analyzed for a series of phosphorus compounds. Atomic charges, atomic energies and properties of the bond critical points are discussed. Low-coordinate phosphorus species, such as phosphaalkenes and phosphenium cations are compared to higher coordinate species. The properties of the electron density, particularly the Laplacian, 2 , can be related to the experimentally observed reactivities of these species.
Saturday Afternoon Session II
Lash Miller Room 159
Session Chair: Scott Browning
2:00 - 2:20 Synthesis and Reactivity of Silica-Stabilized Metal Alkylidenes
Marcel Beaudoin, Jamila Amor Nait Ajjou, Gordon Rice, and Susannah Scott
Department of Chemistry, University of Ottawa, Ottawa (Ontario), Canada K1N 6N5
The gas-solid reactions of volatile organometallic complexes M(CH2R)4, where M is Ti, V or Cr, and R is CMe3 or SiMe3, with the surface of partially dehydroxylated silica yield the chemisorbed species (SiO)2M(CH2R)2, 1. The low temperature thermolysis (<100 °C) of these species results in the clean liberation of one equivalent of RCH3 by a-H elimination with the formation of stable isolated surface metal alkylidene complexes, 2, eq 1.
(SiO)2M(CH2R)2 --------> (SiO)2M=CHR + RCH3 (1)
1 2
The new surface complexes are coordinatively unsaturated and extremely reactive. Reactions with electrophiles, carbonyl compounds and olefins will be presented, as well as evidence for the possible roles of 2 in catalysis.
2:25 - 2:45 Poly(ferrocenylsilane) / MCM-41 Composite Materials
Mark J. MacLachlan, Ian Manners, and Geoffrey A. Ozin
Department of Chemistry, University of Toronto, Toronto (Ontario), Canada M5S 3H6.
Hexagonal, mesoporous silica (MCM-41) has been loaded with strained [1]silaferrocenophanes. Through multiple techniques, the first ring-opening polymerization inside of the ordered channels has been demonstrated. When pyrolysed, iron is left within the channels, forming nanoclusters and nanowires. The resulting ceramic is a magnetic iron / silica composite in which the hexagonal, ordered structure of the silica is preserved. Extraction of the iron nanoclusters and polymer mesofibres may give interesting materials.
2:50 - 3:10 Novel Ce(hfac)3.glyme Complexes for the CVD of CeO2 Films
K.D. Pollard, R.J. Puddephatt, and H. Jenkins
Department of Chemistry, University of Western Ontario, London (Ontario), Canada N6A 5B7.
The CVD of cerium oxide from metal-organic complexes is useful in the catalysis and microelectronics industries. Synthesis of stable complexes with suitable volatility has been only moderately successful. This work describes new Ce(hfac)3.glyme compounds (where hfac=1,1,1,5,5,5-hexafluoro-2,4-pentanedionato, and glyme = monoglyme, diglyme, triglyme, tetraglyme) for the CVD of cerium oxide films. The yellow crystalline compounds were characterized spectroscopically, by elemental analysis, and by thermal gravimetric analysis. The structure of Ce(hfac)3.diglyme has been determined by single crystal x-ray crystallography. Preliminary CVD results will also be discussed.
3:10 - 3:30 Coffee Break
Session Chair: John Powell
3:30 - 3:50 Living Anionic Ring-Opening Polymerization of Phosphorus-Bridged, [1]Ferrocenophanes: Synthesis and Solution Characterization of Poly(ferrocenyl-phosphine) Homopolymers and Block Copolymers
Timothy J. Peckham, Charles H. Honeyman, Jason A. Massey, and Ian Manners
Department of Chemistry, University of Toronto, Toronto (Ontario), Canada M5S 3H6.
The phosphorus-bridged, [1]ferrocenophane Fe(h5-C5H4)2PPh undergoes living anionic ring-opening polymerization to yield monodisperse poly(ferrocenylphosphines) and novel block copolymers with potentially coordinating phosphorus atoms in one segment. The synthesis and characterization of these materials will be reported.
3:55 - 4:15 An Unusual Route to Ring-Opening Polymerization With Palladium Insertion Polymerization Catalysts: Mechanism of a Multi-Functional Cationic Initiator
Ngiap Kie Lim and Bruce A. Arndtsen
Department of Chemistry, McGill University, Montreal (Quebec), Canada H3A 2K6.
The palladium insertion polymerization catalysts (bipy)Pd(CH3)L+OTf– [L = p-Tol(H)C=NPh (1), p-Tol(H)C=NtBu (2), p-Tol(H)C=NCH3 (3), CH3CN (4)] have been found to mediate a second type of polymerization reaction: the ring-opening polymerization of heterocycles. Warming complexes 1-4 to 70°C in the presence of CO and heterocycle (e.g. THF and dioxolane) leads to the formation of ring-opened polymers. The mechanistic details of the polymerization with THF are explored, and show a novel series of metal-based reactions (ligand substitution, CO insertion, nucleophilic ring-opening, reductive elimination) are operative in the ring-opening process. In addition, preliminary experiments on the reaction of 4 with t-butylstyrene, CO and THF at 70°C show these complexes may provide a unique single-step route to combine monomers polymerized by distinct mechanisms, insertion and cationic ring-opening polymerization, into block co-polymers.
4:20 - 4:40 Benzo-bridged Bis(1,2,3-dithiazoles) and Their Selenium Analogues. Preparation, Molecular and Electronic Structures, and Redox Chemistry
K. E. Preuss, R. T. Oakley, and R. W. Reed
Department of Chemistry and Biochemistry, University of Guelph, Guelph, (Ontario), Canada N1G 2W1.
The condensation of diaminobenzenedithiol with sulfur monochloride leads to the chloride salt of the radical cation of 3,6-dichloro-benzo[1,2-d:4,5-d¢]bis(1,2,3-dithiazole), dichloro-[BB-123-DTA][Cl], which can be reduced to neutral dichloro-[BB-123-DTA] with triphenylantimony. A similar condensation with selenium tetrachloride leads, upon reduction, to the corresponding bis(1,2,3-thiaselenazole) dichloro-[BB-123-TSA]. Both compounds, which are formally antiaromatic 16p-systems, exhibit internal bond lengths consistent with a quinoid formulation. The radical cations of both rings have been characterized by ESR spectroscopy. Further oxidation of both rings affords the corresponding dications, both of which have been characterized crystallographically as their AlCl4- salts. These results are discussed in the light of the results of ab initio calculations on [BB-123-DTA].

Lash Miller Room 158
Session Chair: Douglas McIntosh
9:30 - 9:50 Mono and Bridged Phosphine Iron Nitrosyl Complexes
Chris McCrory, Dino Amoroso, and Lijuan Li
Department of Chemistry, McMaster University, Hamilton (Ontario), Canada L8S 4M1.
Iron nitrosyls have been extensively studied due to their wide range of potential applications. The abilities of these compounds to act as catalysts for polymerisation processes had been known for some time. Iron dinitrosyldicarbonyl and iron nitrosyltricarbonyl were synthesized from iron pentacarbonyl. Each was then reacted with various phosphines PR3 (where R = c-C6H11, p-CH3C6H5 or p-CH3OC6H5) or Ph2R’PPh2 (where R’ = CH2CH2 or CH2) substituting the phosphine for one carbonyl resulting in two series of compounds. Each of these phosphine compounds were subject to a subsequent substitution of carbonyl for tetracyanoethylene. Single crystals were isolated and the X-ray crystal structures of Fe(NO)2[P(C6H11)3](TCNE) [1], [Fe(NO)2(CO)2]2dppe [2], and [Fe(NO)2(TCNE)]2dppe [3] were solved and their electrochemical properties were measured.
9:50 - 10:10 Insight into C-S Bond Cleavage Processes in Titanium Thiolate Complexes
Andrea V. Firth and Douglas W. Stephan
Department of Chemistry and Biochemistry, University of Windsor, Windsor (Ontario), Canada N9B 3P4.
Several interesting titanium sulfide complexes have been isolated through C-S bond cleavage reactions. It has been possible to gain information as to the nature of the intermediates involved during sulfide formation by adjusting both the ancillary groups on the metal as well as the thiolate substituents. The mechanism of formation of these compounds will be presented as well as their synthetic potential.
10:10 - 10:30 Multiple Bonds: An Approach to Rare Terminal Chalcogenido Complexes Ligated by Alkylamidinates
Stephen R. Foley and Darrin S. Richeson
Department of Chemistry, University of Ottawa, Ottawa (Ontario), Canada K1N 6N5.
Alkylamidinates provide an abundance of organometallic and coordination compounds of transition and main group metals. We will report on the synthesis and reactivity of a new series of M(II) complexes where M = Cr, Mn, and Ge. The focus has been on the formation of heteronuclear multiple bonds to heavy main group elements (the chalcogens) and the reactivity of these multiple bonds
10:30 - 10:50 Coffee Break
Session Chair: Michael Denk
10:50 - 11:10 Diaminocarbenes and the Role of Steric Stabilization
Michael K. Denk, Ken Hatano, Avinash Thadani, and Martin Ma
Department of Chemistry, University of Toronto, Mississauga (Ontario), Canada L5L 1C6.
Cyclic diaminocarbenes (imidazolylidenes, 1) were obtained from the corresponding thioureas by reduction with potassium [1]. The stability of the carbenes is critically dependent on the steric bulk of the substituents and distinguishes these carbenes from the aromatically stabilized Arduengo carbenes. Details of the carbene dimerization were investigated.

11:10 - 11:30 Novel Dihydrogen Complexes via Protonation of
[RuH(CN)(R2PCH2CH2PR2)2] (R = Et, Ph)
Tina P. Fong, Alan J. Lough, and Robert H. Morris
Department of Chemistry, University of Toronto, Toronto (Ontario), Canada M5S 3H6.
Complexes of the general formula [RuH(CN)(R2PCH2CH2PR2)2] (R = Et, Ph) have been synthesized and characterized. With 1 equivalent of acid, protonation of these complexes can occur at the metal hydrogen bond giving rise to a dihydrogen complex or at the cyanide, resulting in a complex with a hydrogen isocyanide ligand. Protonation of [RuH(CN)(Ph2PCH2CH2PPh2)2] gives rise to [RuH(CNH)(Ph2PCH2CH2PPh2)2]+ while protonation of [RuH(CN)(Et2PCH2CH2PEt2)2] produces [Ru(h2-H2)(CN)(Et2PCH2CH2PEt2)2]+. Further protonation of these complexes with excess acid produces [Ru(h2-H2)(CNH)(R2PCH2CH2PRh2)2]2+.
11:30 - 11:50 Isolobal Substitution of Co(CO)3+ by Fe(CO)3 in Cluster complexes : A Mechanistic Proposal
James A. Dunn, James F. Britten, and Michael J. McGlinchey
Department of Chemistry, McMaster University, Hamilton (Ontario), Canada L8S 4M1.
The aromatic character and relative availability of the fluorenyl, indenyl and cyclopentadienyl anions contrasts with the relative inaccessibility of their corresponding cations. The latter can, however, be stabilized as cobalt cluster complexes. Although these dicobalt cluster cations do not yield X-ray quality crystals, isolobal replacement of a Co(CO)3+ vertex by Fe(CO)3 yields close structural analogues. The mechanism of "dehydroxylation" of cobalt clusters by Fe(CO)5 may instead involve a decarboxylation step, and several trimetallic intermediates have been structurally characterized.
11:50 - 12:10 Organometallic Diacetylide Complexes - Routes into Carbon Toys

Department of Chemistry, The University of Western Australia, Nedlands (WA), Australia 6907.A versatile synthesis of complexes containing the 1,3-diynyl ligand (C∫CC∫CH) will be presented. Bimetallic compounds of general form [MLn]-C∫CC∫C-[M'L'n'] containing a bridging diyndiyl ligand are also readily available. The reactivity of these ligands has been examined in some detail and will be illustrated by several reactions of the complexes W(C∫CC∫CH)(CO)3Cp, [Cp(CO)3W]-C∫CC∫C-[W(CO)3Cp] and [Cp(PPh3)2Ru]-C∫CC∫C-[Ru(PPh3)2Cp].
12:10 - 12:30 Synthesis and Derivatization of Aniline and Phenolic Functionalized Quantum Sized CdS Nanoclusters
Jonathon G. C. Veinot and William J. Pietro
Department of Chemistry, York University, North York (Ontario), Canada M3J 1P9.
Nanosized materials, in particular quantum sized semiconductor particles, have been the focus of extensive research, due primarily to unique optical and electronic properties resulting from the quantum size effect. The realization of novel electronic devices fabricated from such quantum confined semiconductor clusters, otherwise known as quantum dots, would likely necessitate the attachment of other molecular moieties, such as quantum wires, luminophores, or electroactive species, to the cluster surface. In the case of II-V semiconductors, this proves not to be an easy task, as the clusters are quite labile towards many conventional reaction conditions. In this contribution we discuss two effective methods for the covalent attachment of a variety of organic functionalities through the derivatization of aniline and phenol surfaces of a 20 angstrom diameter cadmiun sulfide quantum dot, while maintaining the integrity of the cluster. The synthesis and properties of a few interesting surface derivatized CdS clusters will be discussed.
