Covalent Grafting of Organic–Inorganic Polyoxometalates Hybrids onto Mesoporous SBA-15: A Key Step for New Anchored Homogeneous Catalysts

Richard Villanneau, Asma Marzouk, Yan Wang, Aicha Ben Djamaa, Guillaume Laugel, Anna Proust, Franck Launay

Covalent grafting of heteropolyanions hybrids B,α-[AsIIIW9O33{P(O)(CH2CH2CO2H)}2]5- on 3-aminopropyle functionalized SBA-15 has been achieved through the formation of peptide bonds. The covalent link has been confirmed by using IR and 13C CP MAS NMR spectroscopies. Electrostatic interactions…

Towards metal free supported quaternary ammonium halides catalysts for an optimized cycloaddition of CO 2 onto styrene oxide

Miguel Alonso de La Peña, Matthieu Balas, Julie Kong, Richard Villanneau, Lorraine Christ, A. Tuel, Franck Launay

The present work reports on a large selection of porous siliceous materials functionalised by quaternary ammonium salts (QAS) with various pores structures, possible doping with Zn2+, and different ammonium salt substituents as well as halide counter-ions. After characterization by TGA, N2…

Bisorganophosphonyl and ‐Organoarsenyl Derivatives of Heteropolytungstates as Hard Ligands for Early‐Transition‐Metal and Lanthanide Cations

Richard Villanneau, Aïcha Ben Djamâa, Lise‐marie Chamoreau, Geoffrey Gontard, Anna Proust

Abstract The coordination properties of bisorganophosphonyl and bisorganoarsenyl derivatives of heteropolytungstates towards lanthanides and early‐transition‐metal cations were studied in organic medium. This new class of vacant polyoxometalate (POM) hybrids proved to conserve coordination sites…

Simple procedure for vacant POMs-stabilized palladium (0) nanoparticles in water: structural and dispersive effects of lacunary polyoxometalates

R. Villanneau, A. Roucoux, P. Beaunier, D. Brouri, A. Proust

Metallic palladium nanoparticles have been generated by hydrogenation with H2 of solutions of several non organometallic Pd II-derivatives of heteropolytungstates, at ambient temperature and atmospheric pressure. These nanoparticles have been characterized by various techniques: 31 P NMR and Raman…
