The tri-tert-butoxyaluminum - tert-butyl hydroperoxide system generates molecular oxygen in the electron-excited singlet state (¹O ₂), which oxidizes diphenylamine, N-ethylaniline, aniline, and 2,6-diisopropylaniline to form nitroxyl radicals. The latters were identified by ESR at 240-293 K. Oxidation proceeds via the intermediate formation of nitrogen-containing N-peroxide compounds.
