Cation-radicals in the electrochemical oxidation of 1,2,6-trimethyl-3,5-diacetyl-1,2-dihydropyridines

Abstract

The ESR spectra of the cation-radicals of 4-substituted 3,5-diacetyl-1,2,6-trimethyl-1,2-dihydropyridines were generated electrochemically by oxidation in acetonitrile at −40°C. The unpaired electron distribution in the cation-radicals was established by analysis of the hyperfine structure of the ESR spectra. It was found that the size of the electrochemical oxidation potential of the compounds and the unpaired electron distribution in the cation-radical were subject to the inductive effect of the substituents in positions 3 and 5 of the heterocycle.
