Synthesis, Characterization, Biological and Chelating Properties of New Antipyrine Derived Azo Dyes and its Transition Metal Complexes

Khushbu K. Mehta and Asha D. Patel


4-((1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)diazenyl)-3-hydroxy-2-naphthoic acid (L) (DpAAPBA) has been synthesized from diazotized p-aminoantipyrine (DpAAP) and Bon acid (BA). Transition metal complexes of synthesized ligand with Cu(II), Ni(II), Co(II), Mn(II) and Zn(II) acetate were prepared. The structures of the ligand and its transition metal complexes are investigated by means of their metal-ligand (M:L) ratio, elemental, IR, NMR and mass spectral studies. Further, the structure of metal complexes was confirmed using magnetic measurement and reflectance spectral analysis, which suggest octahedral geometry for all complexes. Also, biological evaluation of all synthesized compound shows moderate to good activity against employed strains.
