Title
Selective hydroxylation of cyclohexene over Fe-bipyridine complexes encapsulated into Y-type zeolite under environment-friendly conditions
Abstract

•Fe-bipyridine complexes were encapsulated into Y-type zeolite ([Fe(bpy)3]2+@Y).•Slightly distorted or compressed [Fe(bpy)3]2+ ions were formed within supercages of Y-type zeolite.•[Fe(bpy)3]2+@Y exhibited high selectivity for hydroxylation of cyclohexene in H2O solvent.•The selective hydroxylation of cyclohexene with O2 oxidant proceeded over [Fe(bpy)3]2+@Y.

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.
