【摘要】 研究了氨基膦酸树脂负载铜配合物(简写为APAR—Cu(Ⅱ))在卤代芳烃及杂环卤代芳烃与咪唑或苯并咪唑的Ullmann反应中的催化性能。实验结果表明,120℃时,以DMSO作为溶剂,KOH作为碱,APAR—Cu(Ⅱ)能较好地催化该偶联反应,反应收率达67%～95%,且可以多次重复使用。更多还原

【Abstract】 The Ullmann reaction of aryl halide or heteroaryl halide and imidazole catalyzed by amino methylene phosphonic acid resin-supported copper complex(abbreviated as APAR—Cu(Ⅱ)) was discussed.The results showed that the catalyst exhibited satisfactory activity when using DMSO as solvent and KOH as base at 120 ℃ and the corresponding coupling products were obtained in good yield between 67%~95% and the complex could be reused for several times.更多还原
