| Abstract: | 2H-Imidazole 1,3-dioxides containing an aldonitrone fragment in the heterocyclic ring are obtained by the oxidation of 5-unsubstituted 1-hydroxy-3-imidazoline 3-oxides. Their further oxidation by lead dioxide in methanol leads to the formation of stable nitroxyl radicals — 5,5-dimethoxy-3-imidazoline-3-oxide-1-oxyls.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2122–2126, September, 1991. |
