Green and versatile! The photocatalytic C(sp2)−H azolation of arenesusingheterogeneouscarbonnitride is reported. This strategy exhibits a broad substrate scope and is amenable to the late-stage functionalization of several pharmaceuticals. The catalyst can be easily recovered and reused leading to greener and more sustainable routes.

The electrochemical synthesis of aryl azoles was performed for the first time in a microflow reactor. The reaction relies on the anodic oxidation of the arene partners making these substrates susceptible for C–H functionalization with azoles, thus requiring no homogeneous transition-metal-based catalysts. The synthetic protocol benefits from the implementation of a microflow setup, leading to shorter
