ELECTROLYTIC OXIDATION OF 2,6-DIMETHYL-3,5-BIS(ETHOXYCARBONYL)-1,2-DIHYDROPYRIDINES IN ACETONITRILE ON PLATINUM ELECTRODES

Free cation radicals, which subsequently undergo deprotonation to neutral radicals and disproportionation to give the starting molecules and pyridinium cations, are formed in the electrochemical oxidation of N-substituted 2,6-dimethyl-3,5-bis(ethoxycarbonyl)-1,3-dihydropyridines on a rotating disk electrode with a ring in solution in acetonitrile.The primary cation radicals were identified by electrochemical generation in a cell placed in the resonator of an EPR spectrometer, and the hyperfine structures of corresponding EPR spectra were studied.

SYNTHESIS AND PROPERTIES OF ETHYL ESTERS OF SOME 1,2-DIHYDROPYRIDINE-3,5-DICARBOXYLIC ACIDS

The oxidation of diethyl 1-methyl- or 1-aryl-2,6-dimethyl-4-aryl-1,4-dihydropyridine-3,5-dicarboxylates with hydrogen peroxide in the presence of perchloric acid gave perchlorates of the corresponding pyridinium ions, the reduction of which with NaBH4 is
