Synthesis and Catalytic Application in Hydrosilylation of the Complex mer-Hydrido(2-mercaptobenzoyl)tris(trimethylphosphine)cobalt(III)

The sulfur-coordinated acyl­(hydrido)­cobalt­(III) complex 1 was synthesized by reaction of thiosalicylaldehyde with CoMe­(PMe3)4. The crystal structure of 1 was determined by X-ray diffraction. Complex 1 is an excellent catalyst for the hydrosilylation of aldehydes and ketones under mild conditions. This might be the first example of hydrosilylation of aldehydes and ketones catalyzed by (hydrido)cobalt complexes.
