The phenylation of diisopropoxydichlorosilane, triisopropoxychlorosilane, and triethoxychlorosilane with chlorobenzene and molten sodium waa investigated. The effect of vai ying the reactant ratio on the yield of diphenyldiisopropoxysilane from the reaction of diisopropoxydichlorosilane, chlorobenzene, and molten sodium was studied. The methylation of triethoxychlorosilane and triisopropoxychlorosilane with methyl chloride ...
