These processes, however, are hampered by the low reactivity of the aliphatic C–H bonds. Photocatalytic processes based on hydrogen atom transfer C–H bond activation strategies have become a useful tool to activate and functionalize these inert compounds. In this article, we summarize the main achievements in this field applied to the development of C–C bond forming reactions, and we discuss the key mechanistic features that enable these transformationeng© 2023 The Authors.
