We report for the first time 2,11-dimethoxyldipyridopurinone (DP4) as a potent reducing visible-light photocatalyst toward three prototypic organic transformations: redox-neutral intramolecular aryltrifluoromethylations of acrylamides and the direct C–H arylation of heteroarenes with aryl diazonium salts, net oxidative hydroxylations of arylboronic acids using molecular oxygen as a green oxidant, and the net reductive dehalogenation/deuteration of α-bromocarbonyl compounds. This work reveals a bright future for dipyridopurinone derivatives as a new class of metal-free visible-light photocatalysts for a wide range of organic transformations.
