Abstract The electrochemical properties of phenazine di-N-oxide (OPO) in acetonitrile solutions in the presence of acids were studied by the method of cyclic voltammetry (CVA). It was shown that OPO forms with a proton a complex having a 2:1 composition, its oxidation and reduction potentials being equal to 1.57 and ∼0.35 V (saturated calomel electrode), respectively. The same protonated form is also formed in the reaction of OPO+. with organic substrates, in particular with hydrocarbons and alcohols. The reaction mechanism includes a complexation of OPO+. with the substrate, followed by splitting off of a hydrogen from the complex by another OPO+· cation-radical or a proton by the initial OPO. A rapid selective deoxygenation of the protonated form of OPO by iodide ion in acetonitrile in an acid medium has been discovered.
