报道了以对甲苯磺酰溴和苯氧基苯-4，4‘-二磺酰溴为引发剂，以CuBr/2，2’-联吡啶(BPY)为催化剂，Cu2O/BPY、Cu2S/BPY、Cu2Se/BPY、Cu2Te/BPY等多种铜基自调节催化体系催化甲基丙烯酸甲酯、丙烯酸丁酯和苯乙烯的活性自由基聚合反应。讨论了芳磺酰氯引发剂和芳磺酰溴引发剂的异同。与相应的芳基磺酰氯引发剂相比，芳磺酰溴引发剂在较温和的反应条件下需要更短的反应时间以高转化率生成聚合物。同时，它们表现出100%的引发剂效率，并产生具有窄分子量分布和官能化链端的聚合物。(C)2004年威利期刊公司。
The metal-catalyzed living radical polymerization of methyl methacrylate, n-butyl acrylate, and styrene, initiated with p-toluenesulfonyl bromide and phenoxybenzene-4,4'-disulfonyl bromide and catalyzed with CuBr/2,2'-bipyridine (bpy) and various self-regulated Cu-based catalytic systems such as Cu2O/bpy, Cu2S/bpy, Cu2Se/bpy, and Cu2Te/bpy, is reported. Similarities and differences between the arenesulfonyl chloride and arenesulfonyl bromide initiators are discussed. The arenesulfonyl bromide initiators require reduced reaction times to produce polymers in high conversions under milder reaction conditions than the corresponding arenesulfonyl chloride initiators. At the same time, they exhibit 100% initiator efficiency and generate polymers with narrow molecular weight distributions and functional chain ends. (C) 2004 Wiley Periodicals, Inc.
