A visible‐light mediated γ‐hydroxyalkylation of ketones via C(sp3)‐H functionalization has been developed under redox neutral conditions. This protocol relies on the iminyl radical‐triggered 1,5‐HAT followed by oxyalkylation of alkenes, wherein C−C and C−O bonds were constructed in one step. This three‐component reaction features mild conditions, wide substrate scope and excellent functional group tolerance, thus providing a facile and highly efficient access to complex valuable ketones.
