Abstract

A method for preparation of a new stable Cu(I) catalyst supported on weakly acidic polyacrylate resin without additional stabilizing ligands is described. A simple and efficient methodology for Ullmann Cu(I) catalyzed C-N cross coupling reactions using this original catalyst is reported. Coupling reactions of 4-chloropyridinium chloride with anilines containing electron donating (EDG) or electron withdrawing (EWG) groups, naphthalen-2-amine and piperazine, respectively, are successfully demonstrated.

摘要

描述了一种制备负载在弱酸性聚丙烯酸酯树脂上的新型稳定Cu(I)催化剂的方法,无需额外的稳定配体。报道了一种使用这种原始催化剂进行Ullmann Cu(I)催化的C-N交叉偶联反应的简单有效方法。分别成功展示了4-氯吡啶鎓氯化物与含供电子(EDG)或吸电子(EWG)基团的苯胺、萘-2-胺和哌嗪的偶联反应。
