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.

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%).
