The electrochemical oxidation of 4,5-diphenyl-2-(p-tolyl)pyrrole (I), 2,5-diphenyl-3-acetylpyrrole (II), and 4,5-diphenyl-2-mesitylpyrrole (III), in the presence of pyridine is described.For these compounds the oxidation performed at the potential corresponding to the first cyclovoltammetric peak shows a charge consumption of 2 F/mole.Compound III leads to the formation of a monomeric oxidized species III' which by reduction with zincagain quantitatively leads to the starting material.Compounds I and II mainly lead to 2,3' dimers, with minor amounts of 3,3' dimers which, at the same potential undergo a further oxidation to a mixture of oxidized products, whose structures have been tantatively assigned on the basis of their chemical behavior.An overall reaction mechanism is proposed.
