Immobilized Vitamin B12 within nanoreactors of MCM-41 as selective catalyst for oxidation of organic substrates

A Comparative Study of Catalytic Activity of Fe, Mn and Cu Porphyrins Immobilized on Mesoporous MCM-41 in Oxidation of Sulfides

“…[4][5][6][7][8] Metalloporphyrins have been investigated extensively for biomimetic oxidation of organic compounds as models of cytochrome P450s due to their innate properties, and also because of existence in many natural and fundamental products. [9][10][11][12] These metallo-complexes are able to catalyze selective oxidation processes with a variety of oxygen donors. [13][14][15] Unfortunately, metalloporphyrins as homogeneous catalysts encountered with some drawbacks, i.e, they may easily be destroyed during the reaction and has little stability toward oxidative degradation and they cannot be easily recovered after the reaction.…”

Selective Oxidation of Cyclohexane to Cyclohexanone Catalyzed by Phenanthroline–CuCl2 Complex

“…The greater demand for oxidation products of cyclohexane and the high-energy intensity of the present process warrant a replacement with a more effective catalytic process. Many catalysts are extensively used [8][9][10][11][12][13][14][15][16][17][18], among which copper catalysts involving coreductants are most common. However, most of them show low selectivity of cyclohexanone or require higher temperature.…”

Synthesis, characterization, and catalytic activity of a polymer-supported copper(II) complex with a thiosemicarbazone ligand

“…Although styrene conversions in heterogeneous systems are comparable with the homogeneous results, the heterogeneous systems showed higher selectivity to benzaldehyde. Additionally, the supported catalyst is expected to have several advantages over the Table 5 provides a comparison of the results obtained for our present catalytic system with those reported in the literature [32][33][34]. The present catalyst exhibited higher conversions compared to the other reported systems.…”
