Abstract
A convenient method for the synthesis of unsymmetrical disulfides under mild conditions in good to excellent yields is based on the use of a readily available organophosphorus sulfenyl bromide as activating agent. The unsymmetrical disulfides can be obtained for l-cysteine derivatives and thiols bearing neutral, basic, or acidic functionalities.
