Abstract

Optically active molybdenum(VI) dioxo complexes bearing hydrosalen derivatives as ligands were synthesized, grafted on the surface of MCM-41 and MCM-48 and examined as catalysts for asymmetric epoxidation. In case of cis-β-methylstyrene and trans-β-methylstyrene moderate enantiomeric excesses of up to 31% can be reached when the reaction is carried out at room temperature. The catalysts can also be applied for non-chiral oxidation reactions.
