Pyridones are important heteroaromatic scaffolds found in natural products and pharmaceuticals and are, therefore, of major interest in organic synthetic chemistry. Here we report the first C-H pyridonation of unactivated (hetero-)arenes, providing a methodology to directly access N-aryl-2- and 4-pyridones. Generation of pyridinium radical cations through single-electron reduction allows for the synthesis of pyridones on structurally complex molecules.
