A CONVENIENT SYNTHESIS OF (TRICHLOROMETHYL)CHLOROSILANES

Abstract
In the presence of a catalytic amount of triphenylphosphine, 1,1,2,2-tetrachloro-1,2-dimethyldisilane reacted smoothly under mild conditions with carbon tetrachloride to produce (trichloromethyl) methyldichlorosilane 1 in good yield. (Trichloromethyl)dimethylchlorosilane was also readily prepared by the triphenylphosphine-promoted transfer of the trichloromethyl group from 1 to dimethyldichlorosilane.
