Imination of Sulfur-containing Compounds: XXXV. New Preparation Method and Oxidative Benzenesulfonylimination of Unsymmetrical Disulfides

A new preparative method of synthesis was developed for unsymmetrical, symmetricaldisulfides consisting in sulfenylation of sodium thiolates with N-arenesulfenyl-N,N'-bis(arenesulfonyl)sulfin-amidines. Imination of unsymmetrical disulfides with sodium chloroamides of sulfonic acids occurs at the more nucleophilic sulfur atom affording N,N'-bis(arenesulfonyl)sulfinamidines and symmetrical disulfides.
