An environmentally friendly electrochemical protocol about cobalt-catalyzed C-H amination of arenes has been developed, which offers a simple way to access synthetically useful arylamines. In divided cells, a wide variety of arenes and alkylamines are examined to afford C-N formation products without using external oxidants, which avoids the formation of undesired byproducts and exhibits high atom economy. Importantly, the reaction can also be extended to gram level with moderate efficiency. KIE experiments indicate that C-H bond cleavage might not be involved during the rate-limiting step.

钴 (II) 催化芳烃与烷基胺的电氧化 C-H 胺化

已经开发了一种关于芳烃的钴催化 CH 胺化的环保电化学协议，它提供了一种简单的方法来获得合成有用的芳胺。在分开的电池中，检查了多种芳烃和烷基胺，以在不使用外部氧化剂的情况下提供 CN 形成产物，这避免了不需要的副产物的形成并表现出高原子经济性。重要的是，该反应还可以以中等效率扩展到克级。KIE 实验表明在限速步骤中可能不涉及 CH 键的裂解。
