Catalysts for Hydrosilylation of Ketones

The hydrosilylation reaction [61], in which a Si-H bond is added across a C=C or C=0 bond, shares many similarities to catalytic hydrogenations. Hydrosilylation

The diiodorhodium acetate complexed to two benzimidazolylcarbene units (1) is a useful catalyst for hydrosilylation of ketones, although a simpler system involves (EtO)2SiMeH and Fe(OAc)2. ... 

Buchwald and coworkers developed a series of titanium complexes into highly efficient catalysts for hydrosilylation of ketones. Esters were catalytically converted to alcohols by catalysts formed through reaction of Cp2TiCl2 with n-Buli, followed by reaction with HSi(OEt)3 [66]. Subsequent studies with chiral Ti catalysts led to highly enantioselective hydrosilylation of ketones [67].
