  Effect of the chemical structure of nitroxyl radicals on their reactivity in the reaction with hydrazobenzene and tetranitromethane

  摘要：

  The reaction rate constants of reduction of stable radicals of different classes by hydrazobenzene in hexane at approximately 20-degrees-C, in the range of 0.4-5.10(3) M-1.sec-1, were determined; a single scale of the oxidative properties of stable nitroxyl radicals was constructed. The rate constants of oxidation of a series of nitroxyl radicals by tetranitromethane in aqueous medium at approximately 20-degrees-C, in the range of 0.06-10 M-1.sec-1, were determined. It was shown that the oxidative properties of the nitroxyl group decrease slightly with an increase in its reducing properties for nitroxyl radicals of the piperidine and imidazoline series in reactions with ascorbic acid and tetranitromethane in aqueous medium, respectively.
