Abstract
The novel μ-iminosilyl complexes Ru2(CO)4(μ-dppm)(μ-SiTol2)(μ-R‘CHNSiTol2) (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, CHCH2). 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.
