摘 要:An efficient and practical synthetic protocol to synthesize nonsymmetrical aryl thioethers by nucleophilic aromatic substitution(S_NAr)reaction of nitroarenes by thiols with potassium phosphate as the catalyst is *** moderate to strong electron-withdrawing functional groups are tolerated by the system to provide thioethers in a good to excellent *** also showed that the present method allows access to 3 drug examples in a short reaction ***,mechanistic studies suggest that the reaction may form the classic Meisenheimer complex through a two-step additionelimination mechanism.
