Abstract

The reactions of sulphuryl chloride with anisole and some methyl-substituted anisoles have been studied kinetically in chlorobenzene as solvent. The reactions have the kinetic form –d[SO2Cl2]/dt=k2[ArH][SO2Cl2], and give almost exclusively the products of nuclear chlorination. The rate is powerfully facilitated by the electron-releasing effect of methyl groups in the nucleus. The results are interpreted as indicating that the reactions are heterolytic, and probably involve electrophilic attack by molecular sulphuryl chloride.
