Reactions of cyclic α-methoxy nitrones, which are derivatives of imidazole or dihydroimidazole N-oxides, with amines, KOH, or KSH result in the replacement of the MeO group to form cyclic α-amino nitrones, hydroxamic acids, or thiohydroxamic acids, respectively. Analogous reactions occur with C-nucleophiles.

The reaction rate constants of reduction of stable radicals of different classes by hydrazobenzene in hexane at ca. 20 deg C, in the range of 0.4 - 5*103 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 ca. 20 deg 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.

A relative scale of the oxidative properties of cyclic nitroxy-radicals has been constructed and the influence of various structural factors on the oxidising capacity of the nitroxy-group in the radicals has been investigated.It is shown that the oxidative properties of the nitroxy-group in cyclic nitroxy-radicals become more pronounced with the increase in ring size.A relation has been established between the oxidative properties and the electron-accepting properties of functional groups separated from the nitroxy-group by two and more ?-bonds.
