Abstract

Abstract Oxidation of 1-hydroxy-5, 5-dimethyl-3-imidazoline-3-oxides containing one or two hydrogen atoms in position 2 of the heterocycle with lead dioxide in alcohol leads to stable nitroxides with alkoxy groups at α-carbon, the derivatives of 2-and 3-imidazolines, via the intermediate formation of 4H-imidazol-1, 3-dioxides.
