Abstract

Abstract An operationally simple and environmentally benign method for reductive coupling of sulfonyl chlorides to the corresponding disulfides has been developed. Sulfonyl chlorides can be rapidly reduced with SO 2/KI/H 2 SO 4 system in moderate to good yields at 80° C in water. Graphical Abstract
