As a highly atom-economical and step-economic strategy, the functionalization of alkane C(sp3)—H bonds to directly convert alkanes into higher value-added chemicals has been a subject of great interest. However, due to the well-known inertness of alkane C(sp3)—H bonds, controlling the chemical selectivity and regioselectivity of non-activated C(sp3)—H bond functionalization poses a significant challenge. Recently, the utilization of hydrogen atom transfer (HAT) for achieving selectivity in C(sp3)—H bond functionalization has attracted renewed attention as a method distinct from traditional transition metal-catalyzed approaches. Herein, various HAT-mediated non-activated C(sp3)—H bond functionalization methods are analyzed based on selectivity of functionalization with a focus on methods that have achieved regioselectivity control. The current limitations of existing methods are summarized and the current challenges and future directions in this field are outlooked.
