Direct synthesis of alkylsilanes by platinum-catalyzed coupling of hydrosilanes and iodoalkanes.

Alkyl iodides and tertiary silanes were successfully coupled with good functional group tolerance using a Pt(P(tBu)(3))(2)/(iPr)(2)EtN/CH(3)CN system. The utility of the methodology is demonstrated by the synthesis of silafluofen, a Si-containing insecticide.
