Abstract
22 Canioni, Romain Marchal-Roch, Catherine Leclerc-Laronze, Nathalie Haouas, Mohamed Taulelle, Francis Marrot, Jerome Paul, Sebastien Lamonier, Carole Paul, Jean-Francois Loridant, Stephane Millet, Jean-Marc M. Cadot, Emmanuel ; {Mo-132} Keplerate anion reacts with tellurites to give a soluble precursor to produce in hydrothermal conditions single-phase M1 MoVTeO light-alkanes oxidation catalyst. Characterization of this Te-containing intermediate by single-crystal X-ray diffraction, Te-125 NMR, UV-visible and redox titration reveals a molybdotellurite anion as a crown-capped Keggin derivative.
