Flavin photocatalysis were utilised for an aerobic oxidative reaction between arylamines and o -phenylenediamine. This metal-free reaction proceeded in methanol under visible light irradiation and consumed only atmospheric molecular oxygen, providing a novel eco-friendly method for the synthesis of benzimidazoles.
