single-electron transfer of α,α,α-trifluoromethyl arenes in the presence of lithium salt to give α,α-difluoroalkylarenes. The C−F bond reduction was realized by lithium iodide and triethylamine, two common feedstock reagents. Computational studies indicated that the lithium-assisted defluorination and the single-electron reduction occurred concertedly. We call this phenomenon fluoride-coupled electron transfer
我们开发了一种电子供体-受体复合物介导的α,α,α-三氟甲基芳烃在锂盐存在下的单电子转移,得到α,α-二氟烷基芳烃。 C−F 键还原是通过碘化锂和三乙胺(两种常见的原料试剂)实现的。计算研究表明,锂辅助脱氟和单电子还原同时发生。我们将这种现象称为氟化物耦合电子转移(FCET)。
