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

Synthesis

Add 4.0 grams of dichlorotris(triphenylphosphine) ruthenium to the 250mL branch-necked bottle, feed nitrogen to replace the air in the branch-necked bottle, and inject 40mL into the branch-necked bottle through three times of liquid nitrogen freezing. Re-thaw the treated dichloromethane; place the side-necked flask in a cold bath at -78°C, and add a pentane solution of phenyldiazomethane with a mass concentration of -50°C of 98.5 mg/mL under stirring conditions 10 mL was mixed, and the phenyldiazomethane in the pentane solution of phenyldiazomethane was the phenyldiazomethane prepared above; the obtained mixture was stirred at -70 °C for 10 min, and then added 40 mL, -50 °C The mass concentration of 0.064 g/mL tricyclohexylphosphine in dichloromethane solution was carried out at 25 °C for 30 min. After the reaction, the obtained reaction solution was filtered to remove insolubles, the filtered reaction solution was concentrated to 10 mL and then filtered again, and 100 mL of methanol that had undergone three liquid nitrogen freeze-thaw treatments was added to the obtained filtered product for precipitation. , the obtained precipitate was first washed three times with methanol and then twice with acetone, and the washed precipitate was vacuum-dried for 3 hours to obtain 2.1 g of 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.

Chemical Properties

bright purple powder

Uses

suzuki reaction

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.

Uses

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

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.

reaction suitability

reagent type: catalyst
core: ruthenium
reaction type: Ring-Opening Polymerization

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.].
