Phenylazo derivatives of some unsaturated beta-diketones and their metal complexes

Phenylazo derivatives of three beta-diketones in which the diketo function attached directly to olefinic linkages (dicinnamoyl methane, acetyl cinnamoyl methane and benzoyl cinnamoyl methane) have been synthesized and characterised. Analytical, IR, H-1 NMR and mass spectral data indicate that the co...

Summary:Phenylazo derivatives of three beta-diketones in which the diketo function attached directly to olefinic linkages (dicinnamoyl methane, acetyl cinnamoyl methane and benzoyl cinnamoyl methane) have been synthesized and characterised. Analytical, IR, H-1 NMR and mass spectral data indicate that the compounds exist in the intramolecularly hydrogen bonded keto-hydrazone form. In the [ML2] complexes [M = Ni-II, Cu-II, Zn-II] the compounds function as monobasic bidentate in which one of the hydrazone nitrogen and keto oxygen are involved in bonding with the metal ion.
