Copper-Catalyzed Direct Synthesis of Aryl Thiols from Aryl Iodides Using Sodium Sulfide Aided by Catalytic 1,2-Ethanedithiol

Abstract

A copper-catalyzed direct and effective synthesis of aryl thiols from aryl iodides using readily available Na2S·9H2O and 1,2-ethanedithiol was described. A variety of aryl thiols were readily obtained in yields of 76–99%. In this protocol, Na2S·9H2O was used as ultimate sulfur source, and 1,2-ethanedithiol functioned as an indispensable catalytic reagent.
