Polymer Supported Vanadium Complexes as Catalysts for the Oxidation of Alkenes in Water

Abstract

Polymer supported vanadium complexes (denoted as c-PMA n -V) were prepared by the complexation of vanadium ions onto a cross linked polyacrylate. cPMA n -V can catalyze the oxidative cleavage of olefins with a large excess of t-butyl hydroperoxide (TBHP) or bishydroxylation of olefins with 4 eq. of TBHP.

Reduction of olefins, nitroarenes and Schiff base compounds by a polymer-supported [2-(2′-pyridyl)benzimidazole]palladium complex

“…Polymer supports have also found significant applications in catalysis [3,4]. Novel porous polymers such as polystyrene divinyl benzene (PSDVB), which has good stability with simple functionalization of organic groups, have been reported [5][6][7][8][9]. Polymer supports associated with nitrogen-containing ligands have been studied because of their stability to oxidation [10].…”

Oxidation of isoeugenol to vanillin by the “H2O2–vanadate–pyrazine-2-carboxylic acid” reagent

“…Vanadium complexes are known as efficient catalysts for various mild oxidations of organic compounds [7][8][9][10][11][12][13][14], particularly, saturated [15][16][17][18][19], aromatic [20][21][22][23] and olefinic [24][25][26][27] hydrocarbons as well as natural products [28][29][30]. In most of these processes, hydrogen peroxide was used as the oxidizing reagent (usually in an air atmosphere); however, the applications of other peroxides, such as tert-butyl hydroperoxide [31,32] and peroxyacetic acid [33], in these oxidations were also described.…”

Oxidative Cleavage of C=C Bond of Styrene and Its Derivatives with H2O2 using Vanadyl (IV) Acetylacetonate Anchored SBA-15 Catalyst

“…Recently, to combine the advantages of both homogeneous and heterogeneous catalytic systems, heterogenization of homogeneous catalysts on solid supports has been initiated [11][12][13][14]. At this juncture, the studies on preparation, characterization and catalytic application of metal acetylacetonate anchored onto porous supports have been under intensive investigation [15][16][17][18][19][20].…”
