Abstract
The present invention relates to novel Ruthenium-based complex compounds which represent viable catalysts, in particular for all sorts of metathesis reactions. Such complex compounds can be prepared by a novel, very favorable and cost efficient method which includes the introduction of an alkylidene ligand into the complex by using vinyl sulfides or vinyl ethers.
