Persistent cyclic acyloxy aminoxyl radicals can be obtained by intramolecular trapping of benzoyl radicals by adjacent aromatic nitro groups whereas analogous intermolecular acyloxy adducts decay by N-O cleavage to give C-nitroso compounds and ultimately acyl aminoxyls.

Hydroperoxides and cobalt-coordinated peroxy-radicals oxidize hydroxylamines as e.g.Et2NOH, (PhCH2)2NOH, PhCH2PhNOH to the respective nitrones, and the spin adducts - nitrone and peroxy-radical - are formed.In contrast to hydroperoxides the coordinated peroxy radicals can oxidize the formed spin adducts, the methylene or methine groups next to nitrogen being converted into carbonyl groups.The radical intermediates corresponding to individual steps of the gradual oxidation have been identified by means of EPR spectra.
