Chemistry & industry

Applications

UsesChlorodiphenylsilane is used in Medicine field, electronics industry, polymer materials. It is used in reduction of alcohols.

UsesOrganolithium and Grignard reagents react with chlorodiphenylsilane to produce substituted alkyl- or aryldiphenylsilanes (eqs 4 and 5).

Preparation methods

Preparationchlorodiphenylsilane may be prepared in high yield by treatment of diphenylsilane with triphenylmethyl chloride in refluxing benzene or with PCl5 at rt in CCl4.
