Description
  • The synthesis and reaction with two oxidation agents is described for N-phenyl-1-(2-oxo-1- azacycloalkyl) methanesulfonamides. Their oxidation was carried out using RO2. 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 -NO.- fragment does not prevent the interaction of the unpaired electron with the methylene protons and the nitrogen atom of the heterocyclic ring.
