Abstract
The N,N′-aryl substituted bipyridinium perchlorates were studied by the methods of cyclic voltamperometry and classical and commutated polarography in DMFA. It was shown that cation-radicals, which are stable in an atmosphere of argon, are formed at the first stage of reduction. The reversibility and the number of the subsequent stages depend on the nature of the substituent at the nitrogen atom. The formation of the bipyridinium cation-radicals was confirmed by the method of EPR spectroscopy.
