This invention relates generally to C—H activated ruthenium olefin metathesis catalyst compounds which are stereogenic at the ruthenium center, to their preparation, and the use of such catalysts in the metathesis of olefins and olefin compounds. In particular, the invention relates to the use of C—H activated ruthenium olefin metathesis catalyst compounds in Z-selective olefin metathesis reactions, enantio-selective olefin metathesis reactions, and enantio-Z-selective olefin metathesis reactions. The invention has utility in the fields of catalysis, organic synthesis, polymer chemistry, and industrial and fine chemicals chemistry.

The present invention describes the use of soluble metal salts to reduce impurities and metathesis catalysts poisons from olefinic feedstocks to improve olefin metathesis efficiency. The soluble metal salts were added to the olefinic feedstocks to prevent peroxides and catalyst poisons from inhibiting the metathesis catalyst. The soluble metal salts remain in the olefinic feedstocks and are used without further purification in the olefin metathesis reactions. The key to this invention is the soluble metal salt compounds do not inhibit the olefin metathesis catalysts but unexpectedly increase olefin metathesis catalyst efficiency while prior art heterogeneous metal complexes sequester the olefin metathesis catalyst, preventing olefin metathesis.
