Abstract
AbstractA new series of β‐ketoanilides, in which the keto group attached to an olefinic linkage, have been synthesized by the reaction of acetoacetanilide with p‐substituted benzaldehydes (4‐methoxybenzaldehyde, 4‐ethoxybenzaldehyde, 4‐dimethylaminobenzaldehyde and 4‐nitrobenzaldehyde) under specified conditions. The existence of these β‐ketoanilides predominantly in the intramolecularly hydrogen bonded enol forms has been well demonstrated from their IR, 1H NMR and mass spectral data. Details on the formation of [ML2] complexes of these compounds with Ni(II), Cu(II) and Zn(II) and their nature of bonding were discussed on the basis of analytical, IR, 1H NMR and mass spectral data.
