Herein, we report the reaction development and mechanistic studies of visible-light-driven Cu-catalyzed dechlorination trichloroacetic acid for highly selective formation monochloroacetic acid. Visible-light-driven transition metal catalysis via an inner-sphere pathway features dual roles species in photoexcitation substrate activation steps, a detailed understanding their is crucial further light-driven catalysis. This catalytic method, which environmentally desired ascorbic as hydrogen atom source water/ethanol solvent, can be applied to dehalogenation variety halocarboxylic acids amides. Spectroscopic, X-ray crystallographic, kinetic have revealed mechanism copper photoexcitation, thermal first C–Cl bond, excited-state second bond chlorine transfer.
