Aluminum chloride catalyzed intramolecular cyclization and allylsilylation of diallylsilanes

Abstract

Reactions of diallylsilanes with allyltrimethylsilane in the presence of aluminum chloride as a catalyst resulted in intramolecularly cyclized allylsilylation, products of trans- and cis-3-allyl-1,1-dimethyl-5-((trialkylsilyl)methyl)-1-silacyclohexanes in good yields. The reaction proceeded faster and gave better yields with the incorporation of chlorotrimethylsilane in the aluminum chloride catalyst.
