Abstract: | Direct oxidation of benzylic alcohols to their corresponding ketones on Cr(ZSM- 5/MCM41) composite materials catalyst with t-BuOOH as terminal oxidant is carried out under microwave irradiation in high yield and with high stereoselectivity. Then the ketones were obtained under solventless conditions on silica gel media, with 80% yield and reaction time 10 min. The Composite materials Cr-(MCM41/ZSM5) used were exchanged at low content of chromium and containing both micropores and mesopores structures and were very selective and stable for this type of reaction. High conversion rates compared to the others catalysts was obtained. |
