Baeyer–Villiger oxidation of cyclic ketones using Fe containing MCM-48 cubic mesoporous materials

Iron containing cubic mesoporous MCM-48 materials were prepared by a modified Stöber synthesis method. These materials were characterized by powder X-ray diffraction (XRD), nitrogen isotherms, diffuse-reflectance UV–Vis spectroscopy, and electron microscopy. These materials exhibited high catalytic activity towards the Baeyer–Villiger oxidation of cyclic ketones using benzaldehyde and molecular oxygen. The Fe-MCM-48 mesoporous materials showed excellent recyclability and the integrity of the cubic phase was preserved after the catalytic activity.
