The distribution of products of benzhydryl bromide heterolysis in the presence of triphenylverdazyl in anhydrous nitrobenzene and propylene carbonate, as well as in anhydrous acetonitrile in the presence of benzyltriethylammonium chloride was studied. In kinetic experiments the contribution of verdazyl alkylation was always minor, and verdazyl was mostly consumed in the reaction with HBr evolved during solvolysis. Thus, triphenylverdazyl is not an indicator of the solvent-separated ion pair of benzhydryl bromide. Pleiades Publishing, Inc., 2006.

A novel design of electroactive components of rechargeable organic batteries based on stable verdazyl radicals bearing various substituents is proposed. 3-Positioned aromatic substituents at the verdazyl moiety affect the reduction potentials and almost do not affect the oxidation potential, while 1-positioned aromatic substituents affect contrariwise the oxidation potential of this radical without any influence on the reduction potential. The acquired electrochemical data allowed us to reveal the structure—potential relationship for the cathodic and anodic processes, which provided the design of triarylverdazyl radicals possessing record-breaking parameters of the “electrochemical gap”.

(Chemical Equation Presented) 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 (Ecell = |Eox° - E red°|) for these radicals; a correlation between the electron spin distribution and redox properties is developed.
