Abstract: Abstract: Biomimetic iron(III) complexes such as [Fe(en)2Cl2]Cl, [Fe(bpy)2Cl2]Cl, [Fe(salen)Cl], [Fe(TPP)Cl] and [Fe(TMC)Cl] in which en, bpy, salen, TMC, and TPP refer to ethylenediamine, 2,2′-bipyridine, N,N′-bis(salicylidene)ethylenediamine), 5,7,12,14-tetramethyl-1,4,8,11 tetraazacyclotetradeca 4,6,11,13-tetraene and meso-tetraphenylporphyrin were immobilized within nanoreactors of Al-MCM-41. The structures of immobilized complexes were characterized by powder X-ray diffraction (XRD), nitrogen adsorption–desorption, FTIR and UV–vis spectroscopy. The pore volume, surface area and pore diameter of Al-MCM-41 were found to decrease after immobilization of iron complexes. It was found that immobilized iron complexes within Al-MCM-41 with the order of [Fe(bpy)2Cl2]>[Fe(TPP)Cl]>[Fe(TMC)Cl]∼[Fe(salen)Cl]>[Fe(en)2Cl2]Cl catalyze the oxidation of cyclohexane to cyclohexanol and cyclohexanone with hydrogen peroxide in refluxing acetonitrile.
