An amino acid coordinated vanadium (IV) complex: Synthesis, structure, DFT calculations and VHPO mimicking catalytic bromoperoxidation of organic substrates

A new VHPO mimicking oxovanadium(IV) complex [VO(sal-l-val)(phen)] (sal-l-val = Schiff base derived from salicylaldehyde and l-valine; phen = 1,10-phenanthroline) has been synthesized and characterized by elemental analysis, UV–vis, IR spectroscopy, ESI-MS, EPR and single crystal XRD studies. The structural and spectral parameters were further supported using DFT calculations. The complex was found to exhibit vanadium dependent haloperoxidase (VPHO) activity.
