Immobilization of organorhenium(VII) oxides

In the last decade considerable progress has been made in research on organorhenium(VII) oxide catalysts, particularly with respect to methyltrioxorhenium(VII) (MTO). Heterogeneous systems have been developed with particular emphasis on the supporting systems including inorganic and organic carrier materials. As a result efficient and reasonably selective catalysts are now available for a variety of catalytic reactions like olefin epoxidation in particular and other oxidation reactions, metathesis, etc. Besides the MTO/UHP system, polymer supports for the organometallic catalysts are now also successfully applicable. The systems exhibit in several cases the required properties of stability, selectivity, activity and recyclability.
