neutral bidentate n-o type complexe of vo(ii) has been synthesized through condensation of dpenicillamine,(d-h2pen), with bis(acetylacetonate)- oxovanadium(iv),[vo(acac)2], at neutralmedium . the established schiff base(no type) complex was characterized on the basis of ir andmass spectroscopy techniques.besides,d-h2pen binding behavior to[vo(acac)2] has been studiedin thermodynamic viewpoint u...
Upon mixing of oxovanadium(IV) acetylacetonate, this complex caused an increase in the chemiluminescence (CL) of luminol in a reverse micellar medium of cetyltrimethylammonium chloride in chloroform-cyclohexane (6:5 vlv)-water (buffered with NaOH-Na2C03, pH 12.5) even in the absence of an oxidizing reagent such as hydrogen peroxide. In this CL process, the reaction of Luminol with the oxovanadi...

In a systematic effort to identify a potent anticancer agent, we synthesized 15 oxovanadium(IV) complexes and examined their cytotoxic activity against 14 different human cancer cell lines. The oxovanadium compounds included mono and bis ancillary ligands of 1,10-phenanthroline (phen) [VO(phen), VO(phen)2, VO(Me2-phen), VO (Me2-phen)2, VO(Cl-phen), VO(Cl-phen)2, VO(NO2-phen), VO(NO2-phen)2], 2,...
Two new tetradentate oxovanadium(IV) and iron(II) Schiff base complexes have been prepared by the interaction of vanadyl(IV) iron(III) acetylacetonate with ligand obtained from reaction ethylenediamine 5?-(N-methyl-N-phenylaminomethyl)-2?-hydroxyacetophenone in methanol. These characterized means different spectroscopic techniques such as UV–visible, FT-IR, mass spectrometry, elemental analysis...
There is an urgent medical need for orally effective drugs to replace insulin injections for the treatment of diabetes mellitus. Vanadium complexes with insulin-mimetic activities have recently been proposed as candidates as new antidiabetic drugs. Following in vitro and in vivo studies on a group of bis(3-hydroxy-4-pyronato)oxovanadium(IV) (1) complexes with VO(O4) coordination mode, bis(allix...
The biaryl coupling of substituted aromatic alcohols and the oxidation of p-hydroquinones with molecular oxygen catalyzed by VO(acac)2 were achieved in good to excellent yields.
This work tested two V2O5-WO3/TiO2 catalysts with different vanadium precursors for selective catalytic reduction (SCR) of flue gas NO using NH3 at 150–450 ̋C. While catalyst A was prepared using ammonium metavanadate (NH4VO3) through incipient impregnation, catalyst B was made according to the solvothermal method using vanadyl acetylacetonate (VO(acac)2) as the vanadium precursor. The catalyti...
This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the co...
