was developed for the amidation of aryl halides by using 0.2-10 mol % of CuI, 5-20 mol % of a 1,2-diamine ligand, and K(3)PO(4), K(2)CO(3), or Cs(2)CO(3) as base. Catalyst systems based on N,N'-dimethylethylenediamine or trans-N,N'-dimethyl-1,2-cyclohexanediamine were found to be the most active even though several other 1,2-diamine ligands could be used in the easiest cases. Aryl iodides, bromides, and
通过使用 0.2-10 mol% 的 CuI、5-20 mol% 的 1,2-二胺配体和 K(3)PO(4), K (2)CO(3) 或 Cs(2)CO(3) 作为碱。发现基于 N,N'-二甲基乙二胺或反式-N,N'-二甲基-1,2-环己二胺的催化剂体系是最活跃的,尽管在最简单的情况下可以使用其他几种 1,2-二胺配体。芳基碘化物、溴化物,在某些情况下甚至芳基氯化物都可以有效地酰胺化。反应中可以容忍多种官能团,包括许多与 Pd 催化的酰胺化或胺化方法不兼容的官能团。
