It was found that the reaction of α-amino nitriles with carbonyl compounds gave the substituted 4-oxoimidazolidines in the presence of basic catalyst. These imidazolidinones were oxidized by hydrogen peroxide: although the imidazolidinones containing an α-hydrogen at the 2- or 5-position gave no radical products, 2,2,5,5-tetrasubstituted imidazolidinones afforded new stable nitroxide radicals. By this method, stable biradicals were also prepared; but, no corresponding stable nitroxide radical was isolated by oxidation of substituted imidazolidine-4-thiones.
