Synthesis of 2H-imidazole 1-oxides and stable nitroxyl radicals based on them
摘要:
2H-Imidazole 1-oxides containing an aldonitrone group in the heterocyclic ring are obtained by the condensation of hydroximinomethyl ketones with ketones and ammonium acetate. Their oxidation with lead dioxide in methanol gives stable nitroxyl radicals - 5,5-dimethoxy-3-imidazoline-1-oxyls.
