Easy, efficient, and economic synthesis of anilines remains an important challenge in synthetic chemistry. In this study, a Ni(OAc)2-bipyridine complex is shown to readily catalyze the amination of aryl halides with ammonium salts under direct excitation of light, allowing a broad array of aryl chlorides and bromides to be converted into the corresponding primary (hetero)arylamines in the absence of
简单、高效和经济地合成苯胺仍然是合成化学中的一个重要挑战。在这项研究中,Ni(OAc) 2 -联吡啶络合物表明在光的直接激发下很容易催化芳基卤化物与铵盐的胺化反应,从而使多种芳基氯和溴转化为相应的伯(杂) 在没有外部光敏剂的情况下的芳基胺。药物分子的后期修饰和伯芳基胺的15 N-标记也通过许多示例进行了演示。光诱导产生 Ni(I)-联吡啶物种被认为是反应中的关键步骤,使 Ni(I)/Ni(III) 循环能够进行催化转换。
