The polarographic potentials of the one-electron reduction of phenazine-N, N′-dioxide and its derivatives to free anion radicals were measured in dimethylformamide. The potentials were in satisfactory linear correlation with the Hammett σ-constants of the substituents and with the energies of the lowest unoccupied π-levels of the molecules. The EPR spectra of the derived anion radicals consisted of components corresponding to the expected splitting by the N and H atoms. To interpret them, calculations were made of the electron density distribution by the Hückel MO method with the McLachlan corrections for configurational interaction. The effect on the polarographic potentials and EPR spectra of bulky α-substituents which removed the NO group from conjugation with the aromatic system was examined. [ABSTRACT FROM AUTHOR] |
