Their oxidation was carried out using $R{\rm O}_{2^\bullet}$ radicals and 3-chloroperbenzoic acid. In both cases, the EPR spectra of corresponding aminoxyl radicals were recorded. Their simulation confirmed that the -SO2- group in the neighbourhood of the - ${{\rm NO}^\bullet}$ - fragment does not prevent the interaction of the unpaired electron with the methylene protons and the nitrogen atom of the heterocyclic ring.
