Abstract:
Diketones are key intermediates for the synthesis of core heterocycles such as isoxazole, pyrazole, flavones, triazole, pyrimidine and benzodiazepines. The β-diketone ligand and its transition metal complexes have been manufactured by ultrasound irradiation. The β-diketone is prepared by using Baker-Venkatraman rearrangement and characterized by physical, spectral and analytical data. The moieties β-diketone compound acts as bidentate ligand and co-ordinate with the transition metal atom through β-diketone system. The synthesized compounds have also been screened for in vitro antibacterial and

Abstract:
The reaction of PcMCl 2 ( M = Zr , Hf ) with β-diketones is reported. 1 H NMR and elemental analysis suggest the substitution of two Cl atoms for two β-diketone fragments takes place as a result of this reaction and the complexes PcM(β-dik)2 are formed. All obtained complexes are stable and highly soluble in most organic solvents. The data from 1 H and 19 F NMR, and UV-vis spectroscopy suggest the coordination of two β-diketone ligands in a cis geometry about the central atom of the macrocycle.
