Abstract Benzene-disulfonylchlorides were converted to the corresponding dialkyl-and diphenylesters, N-alkyl-and N-aryl disulfonamides. The half-wave-potentials E1/2 1 and E1/2 2 were measured and the products obtained on potentiostatic fission at E1/2 1 were isolated and characterized. The electroreduction of benzene-1,4-disulfonic acid-diphenylester in methanol yields phenol in a quantity approximately corresponding to the current passed, but no corresponding quantity of sulfinic acid. In dry acetonitrile, benzene-1,4-disulfonic acid diesters and diamides undergo potentiostatic fission (at E1/2 1) in good chemical and current yields, giving the corresponding monosulfonate-sulfinic acid or…
