Chemistry of Heterocyclic Compounds Aims and scope

Abstract

It is demonstrated by 13C NMR spectroscopy that Β-oxo nitrones (3-imidazoline-3-oxide derivatives) exist in the form of an equilibrium mixture of three tautomeric forms with preponderance of the enolo nitrone and enehydroxylamino ketone forms.
