Oxidation reactions are fundamental and practical processes in synthetic chemistry, and achieving selective and efficient oxidation has been a hot topic in this field. Traditional oxidation methods face several challenges, including poor selectivity and difficulty in controlling reactivity. Selective C—H functionalization, especially the selective transformation of C(sp3)—H bonds, enables precise control over functionalization sites and allows for functionalization at some low-reactivity positions, demonstrating significant advantages in synthetic chemistry. Combining selective C(sp3)—H functionalization with oxidation reactions presents a novel approach for achieving high-selectivity in oxidation processes. Hydrogen atom transfer (HAT) is a commonly used method for transforming C(sp3)—H bonds, typically requiring either photochemical or thermal initiation. This article reviews the progress made in the past five years regarding HAT-mediated photochemical oxidation of C(sp3)—H bonds, briefly introducing the reaction mechanisms and substrate applicability of these new systems, and provides an outlook on the future development of HAT-mediated photochemical C(sp3)—H bond oxidation reactions.
