- Reactions of 1,2-Benzenedisulfinic Anhydride
-
1,2-Benzenedisulfinic anhydride (2) is the first isolable example of an aromatic sulfinic anhydride.Its reaction with simple amines and alcohols is straightforward, the nucleophile (NuH) attacking one of the sulfinyl groups in 2 and forming the ring-opene

Benzene-disulfonylchlorides were converted to the corresponding dialkyl- and diphenylesters, N-alkyl- and N-aryl disulfonamides.The half-wave-potentials E11/2 and E21/2 were measured and the products obtained on potentiostatic fission at E11/2 were isolated and characterized.The electroreduction of benzene-1,4-disulfonic acid-diphenylester in methanol yields phenol in 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 E11/2) in good chemical and current yields, giving the corresponding monosulfonate-sulfinic acid or monosulfonamide-sulfinic acid and alcohol or amine.The passage of further electrical current reduces the sulfinic acids to other, as yet undetermined, products.
