Synthesis, Characterization and Chelating Properties of Novel Metal Chelates Derived from Resacetophenone Containing Azo Dye

Bhavana K. Patel and Sanjay D. Patel

Several transition metal chelates viz. Cu2+, Ni2+, Co2+, Mn2+ and Zn2+ of DAPORA ligands were synthesized and further characterized using metal-ligand (M:L) ratio, elemental analysis, IR and reflectance spectra and magnetic properties. The ligand used in synthesis of metal chelates i.e. 1-(2,4-dihydroxy-5--((5-phenyl-1,3,4-oxadiazol-2- yl)diazenyl)phenyl)ethanone (DAPORA) was prepared by simple diazotization reaction between diazonium salt of 2-amino- 5-phenyl-[1,3,4]-oxadiazole (APO) and resacetophenone (RA). The synthesized ligand was characterized by elemental analysis and spectral analysis. In addition, the antifungal activity of DAPORA and its metal chelates was examined against various fungi.
