An efficient copper-catalyzed double S-arylation of sodium sulfide with aryl halides in PEG-400 has been developed. With CuI as a catalyst and PEG-400 as a solvent, a range of electron-withdrawing or electron-donating aryl iodides and aryl bromides were found to be applicable to the environmentally benign system. The present procedure is mild and tolerant of a variety of functional groups and the steric hindrance of ortho-substituents on aryl halides did not affect the outcome of good to excellent yields.
