Abstract:
The invention relates to a novel, heterogeneous catalyst which is especially suitable for the metathesis of olefins. Said catalyst is fixed on an inorganic carrier and contains at least one active rhenium compound having at least one carbene group and optionally other functional groups. The rhenium compound is bonded to the material used as the carrier by a chemical bond.
Abstract:
The invention relates to a novel, heterogeneous catalyst which is especially suitable for the metathesis of olefins, in addition to the production and corresponding use of the same. Said catalyst is fixed on an inorganic carrie r and contains at least one active rhenium compound having at least one carben e group and optionally other functional groups. The rhenium compound is bonded to the material used as the carrier by a chemical bond. Preferably, a cataly st is used, which corresponds to formula (III) wherein S is a suitable carrier, preferably SiO2, and R1, R2 and R3 independently represent a linear or branched C1-C5 alkyl group, preferably a tert-butyl group.
