The selective functionalization of C—H bonds is one of the core research areas in modern synthetic chemistry. Among these, C(sp3)—H bonds are characterized by high bond dissociation energy and weak acidity, and they are widely present in diverse molecular structures with highly similar chemical environments. Therefore, achieving precise control over their site selectivity remains a significant challenge. The hydrogen atom transfer strategy offers new possibilities for the direct transformation of unactivated C(sp3)—H bonds. In recent years, copper-catalyzed C(sp3)—H bond functionalization reactions using N-fluorinated sulfonamides based on the hydrogen atom transfer strategy have developed rapidly. The research progress in this field is reviewed with focus on reaction mechanisms and substrate scope, and an outlook on future development direc- tions and application prospects is provided.
Key words: hydrogen atom transfer; copper catalysis; N-fluorosulfonamide; C—H bond
