Benzylidene-bis(tricyclohexylphosphine)dichlororuthenium Chemical Properties,Usage,Production

Chemical Properties

bright purple powder

Uses

suzuki reaction

Uses

Catalysis of olefin metathesis including ring-closing of dienes, cross metathesis and ring-opening methathesis polymerizations (ROMP).

Uses

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.

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. J Am Chem Soc 118 9606 1996, Furstner & Langermann J Am Chem Soc 119 9130 1997.] § A polymer supported version is available [Schwab et al. Angew Chem (Intl Edn) 34 2039 1995.].
