We develop an electrochemical nickel-catalyzed aminomethylation of aryl bromides under mild conditions. The convergent paired electrolysis makes full use of anode and cathode processes, free of a terminal oxidant, a sacrificial anode, a metal reductant, and a prefunctionalized radical precursor. In addition, this method exhibits wide functional group tolerance (63 examples), including some sensitive
我们在温和条件下开发了一种电化学镍催化的芳基溴氨甲基化反应。收敛配对电解充分利用阳极和阴极工艺,不含末端氧化剂、牺牲阳极、金属还原剂和预功能化自由基前体。此外,该方法表现出广泛的官能团耐受性(63 个示例),包括一些敏感的取代基和芳族杂环。这种氧化还原中性交叉偶联为形成 C(sp 2 )–C(sp 3 ) 键提供了更环保和合成实用的协议。
