A triazole, 2-(4-amino-5-mercapto-4H-1,2,4-triazol-3-yl)phenol, has been prepared from 2-hydroxybenzoic acid by routine multi-step chemical synthesis. It was then used in synthesizing two different Schiff base ligands (L1 and L2). Their respective oxovanadium (IV) complexes (ML1 ML2) were consequently synthesized characterized experimental techniques like elemental analysis, FTIR spectroscopy, ...

The six-coordinate oxovanadium(IV) complexes [VO(RTPP)(L)] (where R=H, methyl, methoxy and chloro groups and L= methyl and ethyl substituted benzimidazoles) were prepared by reacting the ligands; 2-methylbenzimidazole and 2-ethylbenzimidazole with various VO(RTPP). The complexes were characterized by elemental analysis, IR, UV–Vis and H & C NMR. All complexes show V=O stretching vibrations betw...

A variety of metal complexes have been reported that effect the oxidative cleavage of catechol fl —1 0 ]. These systems serve as models for the reaction catalyzed by catechol 1 ,2 -dioxygenase and protocatechuate 3,4-dioxygenase, enzymes in which the proposed mechanism of oxygen incorporation in­ volves substrate activation by the active site of ferric center [1 1 ]. In 1982, Otsuka et al. [6 ]...
