Reactivity of group 4 benzamidinate complexes towards mono- and bis-substituted silanes and 1,5-hexadiene

Zirconium and titanium bis(benzamidinate) dimethyl complexes were found to be active catalytic precursors for the oligomerization of mono- and bis-substituted silanes. The activation of such complexes, by an excess of MAO or by an equimolar amount of B(C

Reactions of symmetrical and unsymmetrical disilanes in the presence of Cp2MCl2/nBuli ( M = Ti, Zr, Hf)

The reactions of disilanes with catalytic quantities of Cp2MCl2/n BuLi (M = Ti, Zr) and cis-cyclooctene in a disilane/cyclooctene/metal ratio of approximately 30 : ≥ 30: 1 exhibited rapid formation of monosilanes and trisilanes. The product distributions produced from H(PhMeSi)2H, H(BuMeSi)2H (symmetrical disilanes) and from HPh2SiSiPhMeH, HPhMeSiSiMe2H, HPhMeSiSiPrMeH and HPh2SiSiPhH2 (unsymmetrical disilanes) were determined by GCMS in all cases and the trisilanes from HPh2SiSiPhMeH and HPhMeSiSiMe2 H were isolated and characterized spectroscopically. Major and minor isomers of Ph4Me2Si3H2 and Ph5MeSi3H2 (formed from HPh2SiSiPhMeH) and of PhMe5Si3H2 and Ph2Me4Si3H2 (formed from HPhMeSiSiMe2H) were identified. Analysis of the product distribution in these reactions indicated that both Si-Si bond cleavage and Si-H dehydrocoupling of the starting disilane occurs. Rationalization of the product distributions and apparent isomer preferences through both σ-bond metathesis steps and metal silylene intermediates is presented. The rapid reaction of the Si-Si bond in H(SiPhMe)χH was found to be characteristic of the disilane and occurred only to a minor extent in the trisilane and was absent in the tetrasilane.

Synthesis of Oligosilanes by Electrolysis of Hydrosilanes

The novel electrochemical reaction of hydrosilane compounds was investigated for the synthesis of polysilanes.The product obtained by electrolysis of Methylphenylsilane 1a was an oligosilane of Mn=454 (GPC) in 60percent yield, which consisted of Si-Si bonds for the main chain.When diphenylsilane was electrolyzed in a similar manner as 1a, the major product was a dimer in 23percent yield.
