Na2[7,10-nido-C2B10H12] was dissolved in degassed THF (45 mL) giving a purple solution. Excess Na was removed from the reduced carborane solution to give a colourless solution which was then transferred into a Schlenk tube containing [RuCl2(COD)]x (0.780 g, 2.78 mmol) and a large excess of naphthalene. The resulting brown mixture was heated at reflux for 90 min then allowed to cool to room temperature. The brown mixture was filtered through a short silica column eluting with DCM to afford a brown solution, removal of solvent from which yielded a brown solid. This was further purified by column chromatography (1:2 DCM:40-60 petroleum ether), giving a yellow band, followed by preparative TLC (2:1 DCM:40-60 petroleum ether, Rf 0.38) yielding solid. C12H20B10Ru requires C 38.59, H 5.40. Found: C 39.48, H 4.87%.

General procedure: A mixture of fluorinated acid silver salt 6 (2.2eq.) and dichlororuthenium(IV) complex 5 (1.0eq.) was first dried under vacuum (13Pa) at room temperature for 1h. Dry dichloromethane (5mL) was added and the resulting mixture was stirred at room temperature for 3h in the dark. The solids were filtered off and washed with dry dichloromethane (2mL). Evaporation of the solvent afforded the product 7-9.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.20759-14-2,Ruthenium(III) chloride hydrate,as a common compound, the synthetic route is as follows.

EXAMPLE 1 Synthesis of (2,4-dimethylpentadienyl) (ethylcyclo-pentadienyl) Ruthenium and Heat Decomposition Properties Thereof 400 g of zinc was weighed into a four-necked flask. 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%). Oily yellow product: 1H-NMR (500 MHz, CDCl3, deltappm) 5.38 (s, 1H), 4.63 (t, J=2.0 Hz, 2H), 4.52(t, J=2.0 Hz, 2H), 2.70 (d, J=2.5 Hz, 2H), 2.15 (q, J=7.5 Hz, 2H), 1.93 (s, 6H), 1.12 (t, J=7.5 Hz, 3H), -0.09 (d, J=2.5 Hz, 2H) IR (neat, cm-1)

Separately, 200 ml of well dried tetrahydrofuran was fed to a 500 ml flask whose inside had been substituted by argon, and 5 g of dichloro(cyclooctadienyl)ruthenium was injected into the flask and well mixed with the above tetrahydrofuran to obtain a suspension. This suspension was cooled to -78 C. in a stream of argon, and 15 ml of the above synthesized tetrahydrofuran solution of trifluoromethyl cyclopentadienyl sodium was added dropwise to the suspension over 1 hour. The reaction mixture was further stirred at -78 C. for 3 hours and returned to room temperature under agitation over 12 hours. After the reaction mixture was let pass through a neutral alumina column in a stream of argon to be purified and concentrated, it was purified again by a neutral alumina column to obtain 0.2 g of bis(trifluoromethylcyclopentadienyl)ruthenium (yield rate of 30%).
