Abstract
Covalent grafting of the nanoporous molecular sieve MCM-41 with 3- aminopropyl trimethoxysilane and acetyl acetone (acac) successively gave modified MCM-41 (acacAmpMCM-41). Reaction of the resulted material with glycine afforded the corresponding supported glycine Schiff base ligand and subsequent reaction with [bis(acetylacetonato)dioxomolybdenum(VI)] was lead to molybdenum complex supported on MCM-41 through propyl chain spacer. Characterization of the resulting material was carried out with FT-IR, atomic absorption spectroscopy, powder X-ray diffraction and BET nitrogen sorption methods. The XRD and BET analyses revealed that textural properties of support were preserved during the grafting experiments. The resulted material successfully catalyzed the epoxidation of olefins with tert-butyl hydroperoxide to the corresponding epoxides.
