enabled arene C-H trifluoromethylation with the Langlois reagent CF3SO2Na under mild reaction conditions. The merger of electrosynthesis and photoredox catalysis provided a chemical oxidant-free approach for the generation of the CF3 radical. The electrophotochemistry was carried out in an operationally simple manner, setting the stage for challenging C-H trifluoromethylations of unactivated arenes
电化学使芳烃 CH 在温和的反应条件下用郎格鲁瓦试剂 CF3 SO2 Na 发生三氟甲基化。电合成和光氧化还原催化的结合为CF3自由基的产生提供了一种无化学氧化剂的方法。电化学光化学以操作简单的方式进行,为挑战未活化芳烃和杂芳烃的CH三氟甲基化奠定了基础。电化学流形的鲁棒性反映在广泛的范围内,包括富电子和缺电子的苯,以及天然存在的杂芳烃。电光化学CH三氟甲基化进一步通过配备有用于在线流式NMR光谱的操作中监控单元的模块化电流动池在流动中实现,为单电子转移过程提供支持。
