Abstract

Irradiation of a toluene solution of[Ru₂(CO)₆-(μ-dppm)(μ-SiTol₂)] (1) in the presence of an excess of Tol₂SiH₂ produced a μ-silyl complex, [Ru₂(CO)₅(SiTol₂H)-(μ-dppm)(μ-n²-HSiTol₂)] (2), which was further converted to a μ-silane complex, [{Ru(CO)₂(SiTol₂H)}₂(μ-dppm)(μ-n²:n²-H₂SiTol₂)] (3), quantitatively. Complex 3 released Tol₂SiH₂ in the presence of CO to regenerate 2, which finally reverted to 1 under thermal conditions. The X-ray crystal structures of 1 and 3 were determined.
