By developing a sterically hindered fluorinating agent, N-fluoro-N-(tert-butyl)-tert-butanesulfonamide (NFBB), we discovered a conceptually novel base-catalyzed, self-sustaining fluorination of active methylene compounds and achieved an unprecedented high-yield fluorination of highly basic (hetero)aryl and alkenyl lithium species.
通过开发空间位阻氟化剂N-氟-N- (叔丁基)-叔丁磺酰胺(NFBB),我们发现了一种概念性新颖的碱催化、活性亚甲基化合物自持氟化反应,并实现了前所未有的高产率。产生高碱性(杂)芳基和烯基锂物种的氟化。
