Abstract
Selective bis-sulfenylation reactions of aryl dihalides have been achieved by copper- catalyzed C–S coupling reactions under mild conditions of refluxing EtOH (80° C). Employment of disulfides as thiolating reagents enables the production of various bis (phenylthio) benzenes with excellent selectivity, and no products from mono C–S coupling are isolated.
