Thaker, B. T. published the artcileMicrowave assisted synthesis and characterization of unsymmetrical tetradentate Schiff base complexes of VO(IV) and MoO(V), Recommanded Product: 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone, the publication is Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (2011), 84(1), 51-61, database is CAplus and MEDLINE.
Microwave synthesis, is green chem. method, simple, sensitive, reducing solvent amount and reaction time. The attempt was made to synthesize the unsym. tetradentate N2O2 ligands and their VO(IV) and MoO(V) unsym. tetradentate Schiff base complexes by classical and microwave techniques using domestic microwave oven. The resulting unsym. Schiff base ligands (I, X = H, 2-Cl, 3-SO2NH2, L1-L3, resp.) were characterized by different spectral methods. Their complexes with oxocations of VO(IV) and MoO(V) were synthesized and characterized by elemental analyses, conductometric measurements, IR and electronic absorption, 1H NMR spectra, mass spectrometry, ESR spectra, magnetic susceptibility measurement and thermal study. Probably the oxo metal ion is bonded to the ligand through the oxygen and imino nitrogen and the geometry around metal ion is distorted octahedral.
