Abstract

ESI mass spectrometry and 51V-NMR spectroscopy have achieved by MSn experiments, which have allowed specific been used to study the reactions occurring between fragmentations of the peroxidic moiety to be distinguished. bisperoxo vanadates and a number of histidine and histidine- In particular, with [VO52L]–, two distinct modes of like ligands, in aqueous alcoholic solutions. Coordination of decomposition were observed, depending on the presence in one and two molecules of ligand is observed with all the the ligand of a free carboxylic function. – Possible compounds investigated affording [VO5L]– and [VO52L]–, biochemical implications related to vanadium respectively. Characterization of these species has been haloperoxidase enzymes are discussed
