Useful:

• Description: Phenylmethylenebis(tricyclohexylphosphorus)ruthenium dichloride is a ruthenium catalyst. Ruthenium catalysts are highly resistant to polar monomers, enabling the polymerization of many polar monomers to prepare cyclic olefin copolymers. Cyclic olefin copolymers can be widely used in the manufacture of various optical, information, electrical, and medical materials.
• Uses: suzuki reaction Catalysis of olefin metathesis including ring-closing of dienes, cross metathesis and ring-opening methathesis polymerizations (ROMP). First metathesis catalyst to be widely used in organic synthesis. Useful for acyclic diene metathesis polymerization (ADMET), Ring-Opening Metathesis Polymerization (ROMP) of strained cyclic olefins, ring opening metathesis (ROM), olefin cross metathesis (CM) and ring closing metathesis (RCM) of terminal olefins under a variety of reactions conditions.
