Va. Reznikov et Lb. Volodarsky, STABLE NITROXIDES WITH HYDROGEN AT ALPHA-CARBON OF THE NITROXYL GROUP, Tetrahedron letters, 35(14), 1994, pp. 2239-2240
The reactions of 1-hydroxy-3-imidazoline-3-oxides containing hydrogen
in the 2-position with PhLi or PhMgBr lead to acyclic alpha-hydroxylam
inooximes. The oxidation of the latter gives stable acyclic nitroxides
with hydrogen at the alpha-carbon atom.
