An efficient synthetic route for the construction of N2-aryl 1,2,3-triazoles is reported via sequential C–N bond formation and electro-oxidative N–N coupling under metal-free conditions. Readily accessible 2-aminoacrylates and aryldiazonium salts were used as starting materials, and the developed protocol displays excellent functional group tolerance, allowing an extensive range of substrate scope
