Highly selective aqueous heterogeneous oxygenation of hydrocarbons catalyzed by recyclable hydrophobic copper (II) phthalocyanine nanoparticles

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

“…In order to improve the catalytic performance of the MPc or metalloporphyrin, numerous support materials have been employed. [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.…”

Nanomagnet‐Supported Partially Brominated Manganese–Porphyrin as a Promising Catalyst for the Selective Heterogeneous Oxidation of Hydrocarbons and Sulfides in Water

“…However, addition of an equimolar amount of n Bu 4 NHSO 4 (TBAHSO 4 ) to Oxone ® , enhanced the oxidation rate and 45 % yield of the corresponding epoxide was obtained. Although the formation of a new oxidant (TBAOX) under these conditions may be responsible for the increase in rate, the fact that quaternary TBAHSO 4 acts as a stabilizer improving the dispersibility of the catalyst should also be taken into account 14d. When the reaction was carried out with TBAOX, full conversion of the olefin was observed.…”

Recyclable hydrophobic copper (II) phthalocyanine catalyzed N-arylation of imidazoles in dimethylsulfoxide

“…价格低廉、易制备、化学和热力学稳定等优点, 因而有 望用作氧化催化剂 [1][2][3] . 例如, Rezaeifard等 [1] 曾报道了铜 酞菁(CuPc)催化碳水化合物的水相氧化反应. 然而, 有 关将金属酞菁用于催化其它反应的报道很少 [3,4] .…”

“…Phthalocyanine transition metal complexes are important industrial pigments and are considered to be potential oxidation catalysts because of their cheap and facile preparation on large scale and in particular their chemical and thermal stability [1][2][3]. For example, Rezaeifard and coworkers [1] used copper (II) phthalocyanine (CuPc) for the aqueous heterogeneous oxygenation of hydrocarbons. However, few reports exist about other reactions by metal phthalocyanine [3,4].…”
