芳香族化合物的直接C-H功能化方法在各种应用中都有需求,包括农用化学品、药物和材料的合成。在此,我们公开了在好氧气氛下使用吖啶光氧化还原催化剂和三甲基硅氰通过直接C-H功能化构建芳香腈的方法。该反应在室温和温和条件下进行,并已被证明与多种供电子和吸电子基团、卤素、含氮和含氧杂环以及含芳香的药物制剂兼容。
Methods for the direct C–H functionalization of aromatic compounds are in demand for a variety of applications, including the synthesis of agrochemicals, pharmaceuticals, and materials. Herein, we disclose the construction of aromatic nitriles via direct C–H functionalization using an acridinium photoredox catalyst and trimethylsilyl cyanide under an aerobic atmosphere. The reaction proceeds at room temperature under mild conditions and has proven to be compatible with a variety of electron-donating and -withdrawing groups, halogens, and nitrogen- and oxygen-containing heterocycles, as well as aromatic-containing pharmaceutical agents.
