Hydrogen atom transfer (HAT)-mediated functional group migration reactions have emerged as powerful strategies for the selective functionalization of unactivated C(sp3)—H bonds, owing to their excellent atom and step economy. These methods enable efficient structural modification of alkanes and complex molecules, and have therefore attracted significant attention in recent years. Nevertheless, the intrinsic inertness of C(sp3)—H bonds and the minimal bond dissociation energy differences among various sites render precise control of regioselectivity highly challenging. Recent advances in hydrogen atom transfer (HAT)-mediated selective functional group migration of C(sp3)—H bonds are summarized, with a focus on catalytic systems, mechanistic features, and representative transformations including aryl migration, cyano migration, boryl migration, and acyl migration, as well as their applications in late-stage functionalization of complex molecules. Finally, current limitations and technical challenges associated with HAT-mediated functional group migration are outlined, and future opportunities and potential applications in medicinal chemistry and materials science are discussed.

Key words: functional group migration, hydrogen atom transfer, C(sp3)—H bond functionalization, regioselectivity
