In the absence of any additional ligands, the efficient N-arylation of nitrogen-containing heterocycles with aryl iodides catalyzed by relative low catalyst amount of Cu(OAc)2·H2O was developed. This simple catalytic system is involved in the C–N cross-coupling reaction and works for a variety of pyrazole, pyrrole, imidazole, triazole, indole, benzoimidazole, benzotriazole, carbazole, and anilines
在没有任何其他配体的情况下,开发了由相对较低的催化剂量的Cu(OAc)2 ·H 2 O催化的含氮杂环与芳基碘的有效N-芳基化反应。这种简单的催化系统参与C–N交叉偶联反应,适用于各种电子性质不同的各种吡唑,吡咯,咪唑,三唑,吲哚,苯并咪唑,苯并三唑,咔唑和苯胺以及碘代芳基碘。建立了高效的铜(II)催化的N-芳基化方案。
