Description
Amino triphenolate tungsten(VI) complexes have been prepared and they proved to be efficient catalysts in haloperoxidation reactions using hydrogen peroxide as a terminal oxidant and inorganic sources of halides. In particular, interesting results have been obtained in the challenging chloroperoxidation reactivity (catalyst loading down to 0.05% with TONs up to 900). A comparison among three different metal complexes bearing the same ligand (vanadium(V), molybdenum(VI) and tungsten(VI)) showed much better performances of the last complex both on bromo and chloro peroxidations.
