An N-heterocyclic carbene (NHC)/tBuOK system was reported for the photoreduction of mono-fluoroarenes. Mechanistic studies suggest the generation of NHC radical anion as a potent reductant, and the Ar−F bond cleavage proceeds via a concerted mechanism, where single electron transfer, Ar−F bond cleavage and KF bond formation take place simultaneously.
据报道,N-杂环卡宾 (NHC)/ t BuOK 系统可用于单氟芳烃的光还原。机理研究表明,NHC 自由基阴离子的产生是一种有效的还原剂,Ar-F 键断裂通过协同机制进行,其中单电子转移、Ar-F 键断裂和 KF 键形成同时发生。
