Synthesis, Characterization and Catalytic Activity of a Tungsten(VI) Amino Triphenolate Complex

Synthesis, characterization and catalytic activity of a novel tungsten(VI) amino triphenolate complex have been investigated. In particular, a tungsten(VI) amino triphenolate complex has been synthesized and tested in the oxidation of sulfides and cyclooctene, using hydrogen peroxide as terminal oxidant. The catalyst has proved to be air and water tolerant, also showing a good efficiency in terms of yields and selectivity. Moreover, an upgrade of our previous ligand synthesis is herein reported. The new developed procedure allows to obtain the triphenolamine in large scale without the use of chromatography for the intermediates purification.
