A visible-light photocalytic method for the chemoselective transfer hydrogenation of diarylketimines in batch and continuous flow utilizes Et3N as both hydrogen source and single-electron donor. The reaction tolerates other reducible functional including nitriles, halides, esters, and ketones. Continuous-flow processing facilitates straightforward scale-up of the reaction.
