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
描述了一种在没有额外稳定配体的情况下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。报道了使用这种原始催化剂的 Ullmann Cu (I) 催化 CN 交叉偶联反应的简单有效方法。4-氯吡啶鎓与分别含有给电子 (EDG) 或吸电子 (EWG) 基团、萘-2-胺和哌嗪的苯胺的偶联反应得到了成功证明。
