A series of unsymmetricaldisulfides has been prepared by employing a reaction involving a ring opening, nucleophilic attack of a thiol on a 1,2-benzisothiazol-3-one. The benzisothiazolones were in turn prepared by an intramolecular ring closure of an amide on a sulfenyl thiocarbonate. The sulfenyl esters were synthesized as intermediates for preparing mixed-disulfides, but the benzisothiazolone ring
