Abstract
In the primary electrochemical reduction of 1-(nitrophenyl)-3,5-dicarbethoxy-4-phenyl-1,4-dihydropyridine in DMF, free radicals of nitrophenyl type are formed; these are the products of a one-electron reduction of cathode-protonated molecules of the original compound. In alkaline DMF, where cathodic protonation of the initial compound is retarded, union-radicals of the starting material are generated in addition, together with p-nitrophenol free radicals.
