EPR and polarography of nitroazoles. 6. 3-Nitro-1,2,4-triazoles
The electrochemical reduction of eight 3-nitro-1,2,4-triazole derivatives in acetonitrile was investigated by polarography and EPR spectroscopy. Two different signals were recorded in the EPR spectra in the electrochemical reduction of derivative I. The first signal shows up at the potentials of the second wave with a hyperfine structure corresponding to coupling of an unpaired electron with five nitrogen atoms and to a symmetrical distribution of the spin density as shown. Electrochemical generation of the ion radicals was realized in special electrochemical cells that had been previously deoxygenated by successive freezing and thawing of solutions in vacuo and were then filled with argon purified over potassium-sodium alloy.
