Abstract:
3,3'-Bi(2-R-5,5-dimethyl-4-oxopyrrolinylidene) 1,1'-dioxides (R = CF3, Me, Ph, and But), which represent cyclic nitrons linked by the conjugated C = C bond, were shown to be strong electron-acceptors. The mechanism of their electrochemical reduction is the EE-type process including the consecutive formation of radical anions and dianions, which are stable under standard conditions. The radical anions of dinitrons, which are stable at 298 K and whose nitron group is not a part of the aromatic pi-system and is not conjugated with it, were obtained for the first time and characterized by ESR spectroscopy in combination with quantum-chemical calculations.
