The reaction of 1, l-dichlorosilacyclohexane and 1, l-dimethylsilacyclohexane with sulfuryl chloride was studied. The chlorination of 1, l-dichlorosilacyclohexane caused little opening of the ring which was extensive during the chlorination of 1, l-dimethylsilacyclohexane. The distributions of isomers obtained from these cyclic silanes were compared with those obtained by chlorination of n-alkylchlorosilanes. Chlorine atoms on silicon disfavor free- ...
