Formation of benzoylsilanes from the reaction of organosilylcobalt tetracarbonyl derivatives with phenyl-lithium

Abstract
Treatment of organosilylcobaltcarbonyl complexes [R3SiCo(CO)4] with phenyl-lithium gives benzoylsilanes R3SiCOPh, with retention of configuration at silicon; an intermediate adduct [R3SiCo(CO)3COPh] Li+ is probably formed and the salt [(α-Np)PhMeSi*Co(CO)3COPh] N+(PPh3)2(where α-Np =α-naphthyl) has been isolated.
