The hydrosilylation of acetylene (HC<*>CH) with trichlorosilane, triethoxysilane, methyldichlorosilane, methyldiethoxysilane and <*>-hexyldichlorosilane in an inert solvent in the presence of various phosphine complexes of Group-VIII metals such as Ru, Rh, Pd and Pt, as well as chloroplatinic acid, was investigated.Among the complexes studied, RuCl2(PPh3)3, PtCl2(PPh3)2, RhCl(PPh3)3, RhH(PPh3)4 and Pt(PPh3)4 were found to be the catalysts of choice for the selective syntheses of vinyltrichlorosilane, vinyltriethoxysilane, methylvinyldichlorosilane, methylvinyldiethoxysilane and <*>-hexylvinyldichlorosilane, respectively.
