  • Design of New Catalysts for Enantioselective Oxidation Catalysis

  • mcm01

    The development of new and efficient heterogeneous catalysts, combining the selectivity of homogeneous catalysts with the advantages of heterogeneous processes, namely recovery of products and recycling of the promoter, continues to be a priority in chemistry.
    Among possible supports, the family of MCM materials, in particular MCM-41, developed by Mobil in 1992, offers a wide range of advantages, from the ordered structure of hexagonal channels with diameters between 2 and 50 nm and high surface area, to the mechanical stability, and the chemical nature of its walls with the reactive SiOH groups. Among the various metals used as catalysts, molybdenum is one of the most important and many homogeneous and heterogeneous catalysts of molybdenum have been synthesized for use in lots of reactions, including epoxidation. In our work we prepare different mesoporous materials and derivatized them with different ligands for the MoI2(MeCN)2(CO)3 and MoO2Cl2(THF)2 precursor complexes of Mo(II) and Mo(VI), respectively. Once prepared the complexes and the materials, we test their catalytic activity in olefin and allylic alcohols epoxidation in both homogeneous and heterogeneous catalysis.
