Two New Sandwich-Type Polyoxomolybdates Functionalized with Diphosphonates: Efficient and Selective Oxidation of Sulfides to Sulfones
Two sandwich-type polyoxomolybdates Na₈[MO₂{Mo₂O₅(O₃PCH₃C(O)PO₃)}₂] (M = Ni2+ (1); Co2+ (2)) were synthesized by one-pot reaction of Na₂HPMo12O40·14H₂O, 1-hydroxy ethidene diphosphonic acid (HEDP=HOC(CH₃)(PO₃H₂)₂), and (1) NiCl₂/CoCl₂ (2). Compounds 1 and 2 were characterized by single crystal X-ray analysis, X-ray powder diffraction (XRPD), IR spectroscopy, 31P NMR spectra, UV-vis spectroscopy...
متن کاملNanosized mesoporous composite PW12-APTES@KIT-6: An efficient heterogeneous catalyst for selective oxidation of sulfides to sulfoxides and sulfones
Surface of mesostructured silica, KIT-6, was modified by grafting 3-aminopropyl-triethoxysilane (APTES) to have the positive charge, and thus, to provide sites for the immobilization of H3PW12O40 (PW12). This modified-nanosized mesoporous silica (PW12-APTES@ KIT-6) was characterized by FTIR, XRD, BET and TEM. The oxidation of sulfides occurs effectively and selectively with H2O2 as the oxidant...
متن کاملThe first example of direct oxidation of sulfides to sulfones by an osmate molecular oxygen system.
Osmate-exchanged Mg-Al layered double hydroxides catalysed the delivery of two oxygen atoms simultaneously via a 3 + 1 cycloaddition to sulfide to form sulfone directly for the first time, reminiscent of 3 + 2 cycloaddition in asymmetric dihydroxylation reactions.

متن کاملNanoparticle catalysed oxidation of sulfides to sulfones by in situ generated H2O2 in supercritical carbon dioxide/water biphasic medium.
In a one-pot reaction, hydrogen peroxide generated from H(2) and O(2) on a Pd catalyst was utilised as oxidant for the TiO(2) catalyzed conversion of a sulfide to a sulfone. This transformation, where two different nanoparticle catalysts were employed in a supercritical carbon dioxide/water biphasic system, demonstrates the potential of compartmentalising catalytic processes in consecutive reac...
