multiple biologically active ingredients into a single molecule. Here, we report a general transition‐metal‐free selective C−H benzylation of tertiary arylamines in good to excellent yields with a broad substrate scope and high functional‐group tolerance under mild conditions. Besides arylamines, some other benzene derivatives also readily furnished the corresponding diaryl methane derivatives with this
由于杂合系统在药物开发中的重要性,迫切需要将多种生物活性成分组装成一个分子。在这里,我们报道了叔芳基胺的一般无过渡金属的选择性CH苄基化,收率良好至优异,在较温和的条件下具有广泛的底物范围和较高的官能团耐受性。除了芳基胺,其他一些苯衍生物也很容易为该方案提供相应的二芳基甲烷衍生物。一系列的控制实验和理论计算表明,这种无过渡金属的反应是一个脱芳香化-芳香化过程。
