ABSTRACT:
The present invention relates to a novel, heterogeneous catalyst which is suitable, in particular, for olefin metathesis. This catalyst is immobilized on an inorganic support and contains at least one active rhenium compound containing at least one carbene group and, if desired, further functional groups. The rhenium compound is bonded to the material used as support by a chemical bond.
