We report here a strategy for inert C–C bondfunctionalization. Site-specific cleavage and functionalization of a saturated C(sp3)–C(sp3) bond via a visible-light-induced radical process have been achieved. The general features of this reaction are as follows. (1) Both linear and cyclic C(sp3)–C(sp3) bonds with a vicinal arene can be specifically functionalized. (2) One carbon is converted into a ketone
