Abstract:

With bidentate alkoxy alkoxide and alkoxy alcohol ligands, respectively, a series of oxovanadium complexes in the oxidation state +4 is synthesized starting from oxovanadium(V) compounds. The reaction of two or more equivalents of 2-methoxyethanol with VOCl3 in n-hexane yields a mixture of the monomeric oxovanadium(IV) complex cis-[VOCl2(HOCH2CH2OMe-κ2O)(HOCH2CH2OMe-κO1)] and the alkoxide-bridged oxovanadium(IV) dimer syn-[VOCl(µ-OCH2CH2OMe-κ2O)]2, which are separated by fractionated crystallization. The same reaction with 2-ethoxy- and 2-iso-propoxyethanol gives only the alkoxide-bridged oxov

Based on the potential redox and catalytic ability of oxovanadium complexes, our goal was to characterize the physical properties of two such complexes to be used as mediators for laccase.

Abstract:

Oxidative stress plays an important role in the pathogenesis of many serious diseases, including cancer, atherosclerosis, coronary artery disease, Parkinson’s disease, Alzheimer’s disease, stroke and myocardial infarction. In the body’s natural biochemical processes, harmful free radicals are formed, which can be removed with the help of appropriate enzymes, a balanced diet or the supply of synthetic antioxidant substances such as flavonoids, vitamins or anthocyanins to the body. Due to the growing demand for antioxidant substances, new complex compounds of transition metal ions with potential

Abstract:

A new series of oxovanadium(IV) chelates containing bi-and tridentate pyrazol-5-one azo derivatives ligands of the type (I) [VO(L)2] and (2) [VO(L)(H2O)] have been prepared and characterized by elementary analysis, IR, electronic spectra, conductance measurements, and molecular weights. The ligands coordinate through (O-N) donor system as monobasic and bidentate (HL) for the first type and through (0-N-O) donor system as dibasic and tridentate (H2L) for the second type of complexes. The molecular weights, the presence of the (V=O) stretching band around 950 cm -1, and the visible spectra sugge
