Crown ether-appended Fe (III) porphyrin: Synthesis, characterization and catalytic oxidation of cyclohexene with molecular oxygen

A new crown ether appended Fe(III) porphyrin complex was prepared by sulfuryl chloride appended benzo-15-crown-5 to the meso position of meso-5, 10, 15, 20-tetra(4-hydrophenyl)porphyrin, and it was applied to catalytic oxidation of cyclohexene with molecular oxygen without reductant, showing a remarkable catalytic activity (conversion is up to 94%) and selectivity for 2-cyclohexen-1-ol (73%).
