Epoxidation of Alkenes and Oxidation of Alcohols with Hydrogen Peroxide Catalyzed by a Fe (Br8 TPPS) Supported on Amberlite IRA-400

Iron (III) meso-tetrakis(p-sulfonatophenyl)-β-octabromoporphyrin supported on Amberlite IRA400 [Fe(Br8 TPPS)-Ad-400] is a robust and efficient catalyst for oxidation of alkenes and alcohols at room temperature. The catalyst exhibits a high activity and stability in hydrocarbon oxidation by H2O2. The method was useful in the oxidation of various primary, secondary-aliphatic, alicyclic and aromatic alcohols. Both activated and non-activated alcohols were converted into their corresponding carbonyls efficiently and selectively. Aqueous hydrogen peroxide as an environmentally benign oxidant is utilized in oxygen transfer. The oxidation reaction using heterogeneous solid catalysts with H2O2 as oxidants are environmentally friendly routes to produce extensively useful epoxides which are traditionally obtained from capital-intensive or environmentally polluted processes.
