Iridium-Catalyzed Hydrosilylation of Sulfur-Containing Olefins.

Hydrosilylation of various sulfur-containing olefins with (RO)3SiH has been achieved using iridium catalysts [IrX(cod)]2 (X = Cl, SPh). The catalysis is applicable to the chemoselective hydrosilylation of thioacetate, which enables the preparation of an industrially important silane coupling agent.
