N-dealkylation of tertiaryamines via photoredox catalysis and its application in late-stage functionalization. Using the developed method, more than 30 diverse aliphatic, aniline-type, and complex substrates are shown to undergo N-dealkylation, providing a method with broader functional group tolerance compared to methods found in the literature. The scope also includes tertiary and secondary amine molecules
