Aerobic Oxidations Catalyzed by Polyoxometalates

H5PV2Mo10O40 Polyoxometalate Encapsulated in NU-1000 Metal–Organic Framework for Aerobic Oxidation of a Mustard Gas Simulant

“…This confirmed that the vanadium atoms were responsible for the aerobic activity in agreement with previous reports. 48,68,69 To verify the source of oxygen, the reaction was also performed under N 2 atmosphere, where the reaction vial was purged with N 2 instead of O 2, and no reaction was observed.…”

“…Here, we employ the POM, decamolybdodivanado phosphoric acid (H 5 PV 2 Mo 10 O 40 ), immobilized in NU-1000 (Figure left and right) for the catalytic oxidation of CEES. H 5 PV 2 Mo 10 O 40 exists as five inseparable isomers and has been used as a catalyst in peroxide-based and O 2 -based oxidation reactions both homogeneously in solution , and heterogeneously on a variety of support materials. − Notably, this POM has been widely reported for its utility in desulfurization of diesel, , the mechanism of which relies upon an initial electron transfer step from the α-aryl group to reduce the POM . Few reports attempt to immobilize these POMs on crystalline supports to, not only improve stability, but also investigate the structure in detail to tune reactivity.…”

A water soluble heteropolyoxotungstate as a selective, efficient and environment friendly oxidation catalyst

“…[9][10][11][12] Polyoxometalates in particular have been used as catalysts to oxidize a broad range of organic substrates. [13][14][15][16][17][18][19][20] As catalyst recovery is an important consideration for any practical catalytic process, many different methodologies have been used for this purpose, e.g. immobilization of the catalyst onto a solid support, [21][22][23][24][25] inclusion of the catalyst in a solvent anchored supported liquid phase, [26][27][28] and the use of a biphasic (aqueousnonaqueous) liquid medium with or without a phase transfer catalyst.…”
