FREE RADICALS IN ELECTROCHEMICAL RTEDUCTION OF 3,5-DICARBETHOXY-1,4-DIHYDROPYRIDINES WITH NITROPHENYL GROUPS IN POSITIONS 2, 4, AND 6

Article abstract of DOI:10.1007/BF00480834

In the electrochemical reduction of 2,6-bis- and 2,4,6-tris(nitrophenyl) derivatives of 3,5-dicarbethoxy-1,4-dihydropyridine, in the first stage, one of the para-nitrophenyl groups in position 2 or 6 of the heterocycle is reduced.Free radicals have been o
