A nickel catalyzed synthesis of α-aryl-α-trifluoromethyl alcohols B is presented that exploits the condensation of iodoarenes and the redox active ether A via cross-electrophile coupling. A mechanistic study was conducted using a comprehensive computational investigation that was also supported by ad hoc control experiments and showed that the key 1,2-HAT (Hydrogen Atom Transfer) event results in the
提出了一种镍催化合成 α-芳基-α-三氟甲醇B的方法,该方法利用碘芳烃和氧化还原活性醚A通过交叉亲电子偶联进行缩合。使用综合计算研究进行了机械研究,该研究也得到了特别控制实验的支持,结果表明关键的 1,2-HAT(氢原子转移)事件导致形成以 C 为中心的自由基C' ,该自由基模仿了三氟乙醛的反应活性。
