Abstract
o-Bis(alkylsulfonyl)benzenes taken as disulfonylbenzene model substrat es lead unexpectedly, under cathodic reduction performed in aprotic me dia in the presence of an excess of alkyl halide, to an alkylation con comitantly with a monocleavage reaction. The formation mechanism of th ese alkylated aromatic monosulfones is discussed on the basis of an el ectron-transfer reaction between the sulfone anion radical and the org anic halide followed by a radical coupling.
