equilibrium mixture of nitrone and its six-membered ring hydroxylamine tautomer; the ratio of which is found to depend on the substituents. The tautomeric cyclic hydroxylamine has been converted to a new class of nitrones by oxidation with mercury (II) oxide or p-benzoquinone. One of the cyclic hydroxylamine lacking hydrogen at the α-carbons has been oxidized to nitroxide spin label.
