Abstract

The anion radicals formed in the electrochemical reduction of 2,3-dimethyl-quinoxoline and its N,N′-dioxide, the 6-methoxy and 6-chloro derivatives of the N,N′-dioxide, and the preparation quinoxidine in DMF were studied. Polarographic analysis showed that the first step in the reduction is a one-electron step and is reversible for all of the compounds except quinoxidine. However, the EPR spectra of the primary anion radicals were recorded only for 2,3-dimethylquinoxaline and its 1,4-dioxide. For the remaining compounds we were able to obtain anion radicals of only the reduction products, the structures of which in a number of cases were established from the EPR spectra.
