Rapid synthesis of aryl sulfides through metal-free C–S coupling of thioalcohols with diaryliodonium salts

An efficient, general, and highly selective method for the synthesis of aryl sulfides has been developed through metal-free, direct C–S coupling from thioalcohols and diaryliodonium salts. Significantly, the reaction took only 10 min to complete and produced high yields at room temperature. Thus, this methodology proves its value as a versatile synthetic choice for a broad range of aryl sulfides, producing good to excellent yields.
