To [RuCl2(PPh3)3] (360 mg, 0.375 mmol) was added a solution of la (100 mg, 0.375 mmol) in 5 ml of CH2C12 with stirring. The resulting burgundy solution was stirred at room temperature.

11 g of trimethylsilyl chloride was dissolved in 30 mol of well dried tetrahydrofuran in a 300 ml flask whose inside had been substituted by nitrogen, and the obtained solution was cooled to -78 C. 100 ml of a tetrahydrofuran solution (2.0 mol/l) of cyclopentadienyl sodium was added dropwise to the above solution in a stream of nitrogen over 1 hour. The solution was stirred at -78 C. for 1 hour and returned to room temperature over 6 hours. A salt precipitated in the mixture solution was removed by filtration in a nitrogen atmosphere, and the residual solution was distilled to obtain 8 g of trimethylsilyl cyclopentadiene. 0.5 g of metal sodium was mixed with a well dried tetrahydrofuran solution in a 300 ml flask whose inside had been substituted by nitrogen, and the resulting solution was cooled to -78 C. A solution of 2.5 g of the above synthesized trimethylsilyl cyclopentadiene dissolved in 30 ml of tetrahydrofuran was added dropwise to the above solution in a stream of nitrogen over 1 hour and further heated to room temperature under agitation for 3 hours to obtain a tetrahydrofuran solution of trimethylsilyl cyclopentadienyl sodium. Separately, 5 g of dichloro(cyclooctadienyl)ruthenium was dissolved in 200 ml of well dried tetrahydrofuran in a 500 ml flask whose inside had been substituted by nitrogen. This solution was cooled to -78 C., and the above synthesized tetrahydrofuran solution of trimethylsilyl cyclopentadienyl sodium was added dropwise to the above solution in a stream of nitrogen over 1 hour. The resulting solution was stirred at -78 C. for 3 hours and returned to room temperature under agitation over 12 hours. After the solution was let pass through a neutral alumina column in an argon gas atmosphere to be purified and concentrated, it was separated and purified by a neutral alumina column again to obtain 0.9 g of bis(trimethylsilylcyclopentadienyl)ruthenium (yield rate of 13%).

As a common heterocyclic compound, it belongs to ruthenium-catalysts compound, name is Dichlorotris(triphenylphosphino)ruthenium (II), and cas is 15529-49-4, its synthesis route is as follows.

In a glove box, [RuCl2(PPh3)3] (0.25 mmol) was added to a schlenk flask equipped with a magnetic stir bar. The flask was then attached to a schlenk line and 3.4 mL of freshly distilled toluene added. The mixture was then rapidly stirred. A 1.7 mL toluene solution of Ph2PCH2CH2NH2, (0.50 mmol) in an NMR tube was then added via a cannula. Any residue in the NMR tube and cannula was washed into the flask with 1.7 mL of toluene. The light yellow mixture was then heated at 100 C. for 6 h. The yellow suspension that resulted was allowed to cool to RT before collecting the precipitate by filtration under Argon. The precipitate was then washed with 10.0 mL portions of toluene, three times (until colorless). The yellow solid was then dried in vacuo. Yield: 90%. Note: Excessive scraping of the product should be minimised to prevent the build-up of static electricity

After purging the container with argon, 205 ml of 2,4-dimethyl-1,3-pentadiene was added thereto to give a suspension. Then a solution of 30 g of ruthenium trichloride n-hydrate (n: about 3) dissolved in 1000 ml of methanol was dropped thereinto at room temperature over 40 minutes. After the completion of the dropping, the mixture was stirred at room temperature for 30 minutes, then heated to 60 C. and stirred for additional 2 hours. The mixture was once cooled by allowing to stand and then 12 ml of ethylcyclopentadiene was added thereto. The resultant mixture was stirred as such at room temperature for 30 minutes, then heated to 60 C. and stirred for additional 2 hours. After the completion of the reaction, the mixture was cooled to room temperature and the unreacted zinc was removed with the use of a glass filter. Next, it was extracted with hexane (750 ml*1, 300 ml*4). The extracts were concentrated under reduced pressure and the oily product thus obtained was distilled under reduced pressure to thereby give 25.4 g of target (2,4-dimethylpentadienyl) (ethylcyclo-pentadienyl) ruthenium (yield: 76.3%).
