from silicon with alkyl chlorides, propyl and butyl chlorides. During the reaction the alkyl chloride is dehydrochlorinated over the surface of copper originating from the catalyst to afford hydrogen chloride and alkene. The hydrogen chloride formed participates in the formation of the silicon–hydrogen bond in alkyldichlorosilane, and the reaction of silicon, hydrogen chloride and alkene also causes
hydrosilylation of 1-hexene with dichlorosilane, many phosphine complexes of group VIII metals, Ni, Ru, Rh, PD and Pt, were found to be active catalysts, giving n-hexyldichlorosilane exclusively. Tris(triphenylphosphine)chlororhodium was found to be the most convenient and effective catalyst for the selective synthesis of mono-organodichlorosilanes.
