Benzylidene-bis(tricyclohexylphosphine)dichlororuthenium

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.

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.

What are the applications of Application

Phenylmethylenebis(tricyclohexylphosphorus)ruthenium dichloride can be widely used in organic synthesis, the first metathesis catalyst; under a wide range of reaction conditions, it is effective for the ring-opening metathesis of strained cyclic olefins of terminal olefins Polymerization, cross-metathesis and ring-closure metathesis units of olefins and vinyl alcohol decomposition of internal olefins.

Purification Methods

Wash it repeatedly with Me2CO and MeOH and dry it in a vacuum. Alternatively dissolve it in CH2Cl2, concentrate it to half its volume, filter, add MeOH to precipitate it as purple microcrystals. Filter these off, wash several times with Me2CO and MeOH and dry them in a vacuum for several hours. [Scwab et al. J Am Chem Soc 118 100 1996, Miller et al.
