Abstract
It has been found by 1H NMR spectroscopy that 2′,5′-dichloroactoacetanilide (1) exists predominantly in the keto form containing an intramolecular hydrogen bond between the amide proton and the carbonyl oxygen at the γ-position in chloroform solutions. In pyridine, the line broadening of signals suggests a rapid interconversion between the keto and enol forms. Configurations of the enol form are discussed.
