Synthesis and Characterization of Vanadyl Complexes of Heterocyclic Acid Hydrazones

Synthesis and Characterization of Vanadyl Complexes of Heterocyclic Acid Hydrazones

Two acid hydrazones, Furan-2-carbaldehyde nicotinic hydrazone and Furan-2-carbaldehyde benzhydrazone have been synthesised and they are characterized by elemental analysis, IR, NMR and UV spectral analysis. Vanadyl complexes of these two hydrazones were synthesised and characterised by elemental analysis, IR, UV, EPR, molar conductivity and magnetic susceptibility measurements. Spectral data indicates the square pyramidal geometry for the monomeric ve coordinated oxovanadium (IV) complexes with the general formula [VO(L)(OCH3 )].The vanadium complex of the acid hydrazone was studied for its catalytic activity. The complex was found to be a good catalyst in quinoxaline synthesis.
