This paper details the copper-catalyzed N-arylation of π-excessive nitrogen heterocycles. The coupling of either aryl iodides or aryl bromides with common nitrogen heterocycles (pyrroles, pyrazoles, indazoles, imidazoles, and triazoles) was successfully performed in good yield with catalysts derived from diamine ligands and CuI. General conditions were found that tolerate functional groups such as
本文详细介绍了铜催化的π-过量氮杂环的N-芳基化反应。芳基碘化物或芳基溴化物与常见的氮杂环(吡咯,吡唑,吲唑,咪唑和三唑)的偶联成功地用衍生自二胺配体和CuI的催化剂进行了高收率的偶联。发现一般条件可耐受芳基卤化物或杂环上的官能团,例如醛,酮,醇,伯胺和腈。使用本文报道的条件,受阻的芳基卤化物或杂环也被发现是合适的底物。
