Aminoxyl groups or Aminoxyl radicals are chemical species containing the R2N–O• functional group. Aminoxyl is the parent compound of the aminoxyl group of radicals. It is an inorganic radical and a member of reactive nitrogen species. Aminoxyl groups are also known as nitroxyl radicals and nitroxides. However, IUPAC discourages the use of these terms as they erroneously suggest the presence of a nitro group. The radicals are structurally related to oximes (hydroxylamines) and N-oxoammonium salts, therefore they can interconvert via a series of redox steps. Moreover, sterically hindered aminoxyls, such as TEMPO and TEMPOL, are persistent (stable) radicals and find use in a range of oxoammonium-catalyzed oxidations. They are also present as temporary species various polymer stabilizers such as hindered amine light stabilizers and some p-phenylenediamine based antiozonants.
