Electrochemical azolation of 1,2-and 1,3-dimethoxybenzenes with tetrazole, pyrazole and triazole derivatives in MeCN in an undivided cell with Pt electrodes proceeds through the formation of intermediate arenonium cations of the ipso-structure. Nature of the starting arenes and the corresponding intermediate arenonium cations determine composition and yields of the target products.
