The one-electron oxidation of α-(arylazo)triphenylmethanes by cerium(IV) ammonium nitrate (CAN) generated aryl radicals along with the triphenylmethyl cation. When the reaction was carried out in the presence of appropriate radical-trapping agents, such as arenes and olefins, the corresponding addition products were obtained in moderate yield. The oxidation of the arylazo compounds with CAN was accelerated
硝酸铈(IV)铵(CAN)对α-(芳基偶氮)三苯基甲烷的单电子氧化产生芳基自由基和三苯基甲基阳离子。当反应在合适的自由基捕获剂如芳烃和烯烃存在下进行时,相应的加成产物以中等产率获得。通过添加酸加速芳基偶氮化合物与 CAN 的氧化。
