The Chan–Lam reaction remains a highly utilized transformation for C–N bond formation. However, anilines remain problematic substrates due to their lower nucleophilicity. To address this problem, we developed an electrochemically mediated Chan–Lam coupling of aryl boronic acids and amines utilizing a dual copper anode/cathode system. The mild conditions identified have enabled the preparation of a
Chan-Lam反应仍然是C-N键形成的一种高度利用的转化方法。但是,由于苯胺的亲核性较低,因此它们仍然是有问题的底物。为了解决这个问题,我们利用双铜阳极/阴极系统开发了一种化学介导的芳基硼酸和胺的Chan-Lam偶联。所确定的温和条件使得能够以良好的产率和化学选择性制备多种官能化的联芳基苯胺。
