Abstract
Partial chlorination of alkyl-and phenyl-polyhydrosilanes was accomplished using carbon tetrachloride or chloroform as chlorinating agent in the presence of benzoyl peroxide at 80°C in a yield ranging from 50 to 80%. The method will be widely applicable for the chlorination of hydrosilanes, since free radical-catalyzed disproportionation between the phenyl and hydrogen radicals attached to the silicon does not take place during the treatment. It was also shown that carbon tetrachloride was suitable for the partial chlorination of phenylpolyhydrosilanes, and chloroform for that of alkylpolyhydrosilanes.
