Oxidovanadium(V) amine bisphenolates as epoxidation, sulfoxidation and catechol oxidation catalysts

Abstract

<p>Air-stable oxidovanadium(V) complexes with tetradentate amine bisphenolate ligands were made by the reaction of VOSO₄·xH₂O and ligand precursors in MeOH solutions. Isolated compounds were studied as <a href="https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-biology/catechol-oxidase" title="Learn more about Catechol oxidase">catechol oxidase</a> models as well as catalysts for epoxidation and sulfoxidation reactions. All compounds can catalyse such oxidation reactions without notable structure-activity correlations. The ⁵¹V NMR studies indicate that the complexes turn to the number of different species during the catalytic experiments.</p>
