Résumé en anglais

Polyoxometalate (POM)-based micellar catalysts were prepared by assembling the Keggin tri-anion [PW12O40](3-) and (L)-N-acetylmethioninate salts of Gemini surfactants in water. Contrary to conventional catalytic systems, we propose a new approach in which the POM catalyst and the substrate to be oxidized ((L)-N-acetylmethioninate) are both localized at the surface of micelles by electrostatic interaction before the reaction. The high local concentration of reactants due to their confinement at the surface of micelles enhances the reaction kinetics. Catalyst recovery experiments showed that, after two cycles of reactions, the activity of the catalysts was not changed. (C) 2014 Elsevier B.V. All rights reserved.< Réduire
