The redox properties of verdazyl radicals are presented using cyclic voltammetry techniques. These radicals can be reversibly reduced as well as oxidized. Electron-donating and -withdrawing substituents have significant effects on the oxidation and reduction potentials as well as the cell potential (E-cell = |E-ox(degrees) - E-red(degrees)|) for these radicals; a correlation between the electron spin distribution and redox properties is developed.

hydrazine fragment, can be involved in the reaction. Further evidence in favor of a radical mechanism of this transformation was obtained using a 3,5-bis(trifluoromethyl)phenylhydrazine derivative. The structural features of the synthesized products were studied by X-ray diffraction analysis.
