Abstract

Fe-bipyridine complexes encapsulated into Na-Y ([Fe(bpy)₃]²⁺@Y) were prepared and their catalytic activities for oxidation of cyclohexene with hydrogen peroxide in CH₃CN and H₂O solvents were investigated. The prepared [Fe(bpy)₃]²⁺@Y was characterized by several methods and it was found that slightly distorted or compressed [Fe(bpy)₃]²⁺ ions were formed within supercages of Y-type zeolite. [Fe(bpy)₃]²⁺@Y catalyst exhibited both higher activity and higher selectivity to 2-cyclohexen-1-ol in water solvent than another Fe catalysts. In addition, the selective hydroxylation of cyclohexene to 2-cyclohexen-1-ol with molecular oxygen was successfully achieved for [Fe(bpy)₃]²⁺@Y catalyst.
