A new, general ortho/para-selective anodic dehydrogenative cross-coupling of two aryl amines, naphthalen-2-amine derivatives and anilines, is described. This electrochemical protocol assembles a wide range of unsymmetrical biaryls in good to excellent yields under mild, additional-metal-catalyst-free, oxidant-free conditions with excellent selectivity, broad substrate scope, and wide functional group
描述了两种芳基胺,萘-2-胺衍生物和苯胺的新的一般的邻/对选择性阳极脱氢交叉偶联。该电化学方案可在温和的,无附加金属催化剂,无氧化剂的条件下,以优异的选择性,宽泛的底物范围和宽泛的官能团耐受性,以良好的产率组装各种不对称的联芳基。通过将重要的药效基团容易地掺入到最终的联芳基中,这一电化学技术得到了突显,并且适用于苯胺的均偶联以生产对称的联芳基。
