Insertion reaction of dimethylsilylene into Si—H and Si—OR bonds

Abstract

Dimeyhtylsilylene generated by photolysis of dodecamethylcyclohexasilane inserts sequentially into Si—H and Si—OR bonds of monosilanes to give high yields of the corresponding unsymmetrical di-, tri- and tetrasilanes. Realtive reactivities of Si—H, Si 2—H, Si—OR, Si 2—, and Si 3—OR bonds toward insertion of dimethylsilene have been determined.
