photoredox-catalyzed hydrotrifluoromethylation of unsaturated systems under continuous flow. This metal-free method is easily broadened to other perfluoroalkyl groups (RF = CF3, CFCl2, CF2Br, C4F9) thanks to the use of sulfilimino iminiums as sources of ·RF radicals. The mild reaction conditions are compatible with unactivated alkenes bearing a wide range of functionalities, as well as with alkynes for the
我们在此报告了一种在连续流动下的不饱和系统的新型光氧化还原催化氢三氟甲基化。由于使用硫亚胺鎓作为·RF 自由基的来源,这种无金属方法很容易扩展到其他全氟烷基(RF = CF3、CFCl2、CF2Br、C4F9)。温和的反应条件与具有广泛功能的未活化烯烃相容,并首次与炔烃相容。
