Reactions of metallated 1-hydroxy-2,2,4,5,5-pentamethyl-3-imidazoline with electrophilic reagents followed by oxidation result in mono- and bifunctional substituted nitroxides of 3-imidazoline and an imidazolidine series including enaminocarbonyl and -thiocarbonyl derivatives and enaminoimines, the spin-labeled chelating reagents.

The reaction of 4-(2R-1-chloro-2-oxoethylidene) -substituted imidazolidine-1-oxyl with sodium azide gives monoimines of alpha -diketones, derivatives of 3-imidazoline nitroxides. Reactions of these products with nitrogen binucleophiles were used to prepare various heterocyclic compounds containing an imidazoline nitroxide moiety.
