Abstract

The reactions of OsH(Ph)(CO)L ₂ (L = P ^tBu ₂Me) with HSiMe ₃, H ₂SiPh ₂ or H ₃SiPh produce benzene and OsH ₃(silyl)(CO)L ₂, which is characterized as a fac-H ₃OsP ₃ shape capped on the H ₃ face by the silyl group. For H ₂SiPh ₂ and H ₃SiPh, these reactions are shown proceed through an intermediate Os(H) ₂(silylene)(CO)L ₂ species. OsHF(CO)L ₂ reacts with these silanes to give the same OsH ₃ product (and silyl-F). These reactions can be combined to effect osmium catalysis of conversion of SiH + H ₂CCHF to fluorosilane and H ₂CCH ₂ from OsH ₃(SiMe ₃)(CO)L ₂, or from the catalyst precursor OsHF(CO)L ₂.
