Abstract

The novel μ-iminosilyl complexes Ru₂(CO)₄-(μ-dppm) (μ-SiTol₂)(μ-R′CH=NSiTol₂) (2) were obtained in high yields during the stoichiometric reactions of a diruthenium complex having Ru-H-Si interactions, {Ru(CO)₂(SiTol₂H)}₂(μ-dppm)(μ-η²:η²-H₂SiTol₂) (1), with nitriles R′CN (R′ = Me, Ph, t-Bu, CH=CH₂). The catalytic hydrosilylation of various ketones and imines with dihydrosilanes were achieved using 1 as a catalyst. A novel reaction cycle involving the cooperative functions of the two Ru metals is proposed for the related hydrosilylation of various ketones and imines catalyzed by 1.
