Electrolysis. -The electrochemical N-arylation of various less basic and more acidic azoles (as compared to pyrazole and dimethylpyrazole), e.g. nitropyrazole (II), triazole and tetrazole, with dimethoxybenzene (I) is studied. The influence of the electrolysis parameters on the reaction outcome is determined and a reaction mechanism is proposed. In contrast to more basic azoles, the presence of tetraalkylammonium salts or collidine is necessary for smooth reaction (only current efficiencies are given instead of yields). -(CHAUZOV*, V.
