mild, general, and efficient copper-catalyzed system for C–S bond formation with high chemoselectivity and wide functional group tolerance is developed. With CuBr as catalyst and 1,2,3,4-tetrahydro-8-hydroxy-quinoline as ligand, the S-arylation of thiols with aryl halides performed well, the activated aryl iodides could take place even at room temperature, and the activated aryl bromides and chlorides
开发了一种温和,通用,有效的铜催化体系,用于形成具有高化学选择性和宽泛的官能团耐受性的C–S键。以CuBr为催化剂,1,2,3,4-四氢-8-羟基喹啉为配体,硫醇与芳基卤化物的S-芳基化反应良好,即使在室温下也可以发生活化的芳基碘化物。芳基溴化物和氯化物也能以良好或优异的收率得到相应的产物。
