interest due to their unique properties. However, the direct radical fluorosulfonamidation process for the synthesis of sulfamoyl fluorides has been overlooked. We herein disclosed a practical procedure for constructing a redox-active fluorosulfonamide radical reagent named fluorosulfonyl-N-pyridinium tetrafluoroborate (PNSF) from SO2F2. These reagents can facilitate a range of reactions, including the N-(fluorosulfonyl)
磺胺酰氟作为 SuFEx 的重要组成部分,由于其独特的性质而引起了广泛的研究兴趣。然而,合成氨磺酰氟的直接自由基氟磺酰胺化过程却被忽视了。我们在此公开了从SO 2 F 2构建氧化还原活性氟磺酰胺自由基试剂、名为氟磺酰基-N-吡啶鎓四氟硼酸盐(PNSF)的实用程序。这些试剂可以促进一系列反应,包括(杂)芳烃的N- (氟磺酰基)磺酰胺化、连续自由基立体选择性氟磺酰胺化和烯烃的 1,2-双官能化。
