Abstract
AbstractThe first metal‐free catalyzed C−H selective fluorination of benzotriazole amides and sulfonamide derivatives was achieved at the C‐7 position using NFSI (N‐fluorobenzenesulfonymide) as the fluorine source. The control experiment showed that the reaction underwent a free radical process that tolerated an excellent range of substrates with mild to good yields (>46 examples, yield up to 71 %).
