TAUTOMERISM IN THE SERIES OF ALKYLARYLHYDRAZONES OF METHYL 4-PHENYL-2,4-DIOXOBUTYRATE

By IR and PMR spectroscopy it was shown that methyl 2-(alkylarylhydrazono)-4-phenyl-4-oxobutyrates exist in solutions as tautomeric mixtures of ketoimine and ketoenamine forms.The tautomeric equilibrium is shifted toward the ketoimine form with the introduction of electron-donating substituents into the aromatic ring at the second nitrogen atom.The logarithms of the constants of the tautomeric equilibrium correlate with the ?+ constants of the substituents.Increase in the volume of the alkyl substituent at the second nitrogen atom has little effect on the position of tautomeric equilibrium.
