Abstract

Abstract It is known that sulfuryl chloride reacts with alkyl-benzenes by a homolytic reaction mechanism and the chlorination occurs exclussively at side chains, particularly in the presence of peroxides1. Bolton reported electrophilic chlorination of alkylbenzenes by SO2-Cl2 in nitromethane as a solvent2. We now wish to communicate electrophilic chlorination of alkylbenzenes occurring by SO2-Cl2 in n-hexane or in CCl4 as solvents even in the presence of peroxides, if a small amount of silica gel is added to the reaction mixture.
