Abstract
The method of EPR under conditions of the electrochemical production of free radicals of N-unsubstituted derivatives of 1,4-dihydro-3,5-dinitropyridine was utilized to confirm the formation of dianion-radicals, and their structure was established. The methods of polarography and cyclic voltamperometry were utilized to show the possible formation of anion-radicals of the N-substituted derivative of 1,4-dihydro-3,5-dinitropyridine which, however, could not be registered by the method of EPR due probably to the π-dimeric diamagnetic state of these species.
