Abstract
The invention relates to penta- and hexacoordinated ruthenium and osmium carbene catalysts, in which a sulfur, oxygen or nitrogen atom is attached to the carbene group which is coordinated with the central ruthenium or osmium atom, to their preparation and to their use for synthesizing polymers, for ring-closing metathesis of olefins and for isomerizing olefins.
