Transition metal complexes containing bidentate O,O donor ligand, i.e. 3-[3-(4-chlorophenyl)4-hydroxy-6-methyl-pyran 2-one derived from 3-acetyl-6-methyl-pyran-2,4(3H)-dione (dehydroacetic acid) and p-chlorobenzaldehyde,have been synthesized and characterized by elemental analyses, conductometry, thermal analysis, magnetic,IR, UV-Vis and fungicidal study. From the analytical and thermal data, t...

The condensation of dehydroacetic acid and 4-hydroxy-6-methylpyran-2-one with primary diamine derivatives such as hydrazine, 1,2-diaminoethane 1,6-diaminohexane yielded bispyrone bispyridone has been reported. hydrazine in acetonitrile generated another bispyrazole product but n-butanol, this reaction afforded the bispyridones. structures synthesized bispyrazoles were examined by spectroscopy X...

Tetradentate complexes of Zn (II) Schiff bases derived from DHA, o-phenylenediamine, 4- N, Diethyl amino Salicylaldehyde (L1) and Dehydroacetic Acid (DHA), 4-methyl-o-phenylenediamine, 5-bromo (L2) have been synthesized characterized by elemental analysis, magnetic susceptibility, thermal X-ray diffraction, 1HNMR, Mass, IR,UV visible spectra conductometry. The ligand field parameters found to o...
