Electrochemical oxidation of substituted 3,4-dihydro-2-pyridones at a rotating graphite electrode with a ring

Using the method of a rotating disk (graphite) electrode with a ring, UV spectroscopy, and prolonged electrolysis, it has been shown that the first stage of the electrochemical oxidation of substituted 3,4-dihydro-2-pyridones in anhydrous acetonitrile corresponds to a two-electron process taking place by an ECE mechanism and leads to the formation of the corresponding substituted 2-pyridones. The potentials of the electrochemical oxidation of the 3-cyano and 3-carbamoyl derivatives of the reduced forms and the potentials of the electroreduction of the corresponding oxidized compounds have been determined.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 87–91, January, 1984.
