Silica-supported molybdenum surface complexes were prepared by the reaction between (N≡)Mo(OtBu)3 and silica via displacement of the tert-butoxy ligands for siloxyls from the silica surface. The structure of the surface molybdenum complexes was well defined by in-situ FT-IR, elemental analysis, 1H NMR and 13C CP/MAS NMR techniques. The surface complexes could undergo alcoholysis reaction with CD3OD and CH3OH in the same way as free (N≡)Mo(OtBu)3 and they show high catalytic activity and selectivity in olefin epoxidation. Initial rates up to 24.9 mmol epoxide (mmol Mo)-1 min-1 were achieved in the epoxidation of cyclohexene using TBHP as oxidant.
