Amine-derived radicals, formed through photocleavage of aromatic ketones containing amine moieties, or by electron transfer between tertiary amines and the triplet state of carbonyl compounds readily undergo the electron transfer processes and subsequent chemistry usually performed with metal-containing photoredox catalysts, but under entirely metal-free conditions.
