MoO2(acac)2 Supported on MCM-41: An Efficient and Reusable Catalyst for Alkene Epoxidation with tert-BuOOH

A new heterogeneous catalyst prepared by immobilization of MO2(acac)2 on Mobil Catalytic Material, MCM-41, is reported. This catalyst, MoO2(acac)2-MCM-41, was successfully applied for efficient epoxidation of olefins with tert-BuOOH in 1,2- dichloroethane as solvent. The catalyst was characterized by elemental analysis, FT-IR, UV-Vis, X-ray diffraction (XRD), and scanning electron microscopy (SEM). This catalyst can be reused several times without significant loss of its catalytic activity
