Mechanism of the disproportionation of organylsilanes in the presence of aluminum chloride

Abstract

1. A mechanism of the disproportionation of trimethylbenzylsilane in the presence of aluminum chloride through intermediate four-center states was proposed and experimentally substantiated. 2. It was proposed that the intermediate products of the reaction are organoaluminum compounds. The formation of side products of the reaction — trimethylchlorosilane and dimethylbenzylchlorosilane — is associated with their presence. 3. The possibility of alkylation of halogen compounds by organylsilanes in the presence of aluminum chloride was discovered.
