We report the hydrofluorination of unactivated alkenes using N-fluorobenzenesulfonimide as a fluorination reagent. The reaction produces exclusively Markovnikov hydrofluorination products under mild conditions. It is not affected by air or moisture and uses an inexpensive and readily available nickel compound as a catalyst. Distinct from the previously reported ionic pathway of the NiH-catalyzed hydrofunctionalization of olefins, this reaction was shown to proceed through a hydrogen atom transfer pathway.

镍催化通过HAT途径催化未活化烯烃的氢氟化

我们报告了使用N-氟苯磺酰亚胺作为氟化试剂对未活化烯烃进行氢氟化。该反应仅在温和条件下产生马尔可夫尼科夫氟化氢产物。它不受空气或湿气的影响，并使用廉价且易于获得的镍化合物作为催化剂。与先前报道的NiH催化的烯烃加氢官能化的离子途径不同，该反应显示为通过氢原子转移途径进行。
