materials, and there has been a growing interest in new synthetic methods for their preparation. In this paper, we report a direct cross-coupling reaction of heteroarenes with N,N-dimethylanilines in the presence of copper catalyst. Oxygen and/or air are successfully used as the oxidant, which is of great importance to the industrialized economies. The reaction is compatible with a wide range of heterocycles
含氮杂环化合物是药物和功能材料的重要主题,并且对用于其制备的新合成方法的兴趣日益浓厚。在本文中,我们报道了在铜催化剂存在下杂芳烃与N,N-二甲基苯胺的直接交叉偶联反应。氧气和/或空气已成功用作氧化剂,这对工业化经济至关重要。该反应与宽范围的杂环相容,包括吲哚嗪,咪唑,吲哚和苯胺,从而能够在非常温和的反应条件下形成各种烷基化的杂芳烃。
