Abstract

original image

Coupling on sunshine: A simple and efficient synthesis of benzoxazoles, benzimidazoles, and benzothiazoles is realized through a one-pot preparation driven by a photocatalytic cascade reaction. Carbon nitride and visible light are employed to achieve this metal-free aerobic oxidation of amines to imines (see scheme; mpg-C3N4=mesoporous graphite carbon nitride).
