position α to the radical centre are formed on oxidation of 4H-imidazole mono- and di-N-oxides in ethanolic solutions of NH3 and CH3NH2. α-Fluorinated imidazolidine nitroxides have been obtained from 3-imidazoline-3-oxide derivatives by treatment with XeF2 in CH2Cl2. Nucleophilicsubstitution of the fluorine atom resulted in formation of aminoimidazolidine nitroxides.

Electrochemicalmethoxylation of substituted 4H-imidazole 1,3-dioxides has been carried out for the first time. Nitroxyl radicals of the 2- and 3-imidazoline series with methoxy groups at the α-carbon atom of the radical site were synthesized. The yields and ratios of the electrochemicalmethoxylation products are close to those observed in the chemical methoxylation carried out with PbO2 and MnO2
