Spectra and Keto-Enol Equilibrium of Benzoylacetanilides

A series of twelve monosubstituted benzoylacetanilides have been prepared by condensation of acetoacetanilide with substituted benzoylchlorides. IR and UV spectral data are presented and discussed. The benzoyl CO stretching frequencies were correlated with σ+ (\barv=34.97σ++1705; r=0.983). The effec...

Summary:A series of twelve monosubstituted benzoylacetanilides have been prepared by condensation of acetoacetanilide with substituted benzoylchlorides. IR and UV spectral data are presented and discussed. The benzoyl CO stretching frequencies were correlated with σ+ (\barv=34.97σ++1705; r=0.983). The effect of substituents in the benzoyl moiety on the keto-enol equilibrium, has also been investigated. The data were correlated by the equation: logK=0.865σ+−0.615; r=0.988.
