With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.50982-12-2,Dichloro(cycloocta-1,5-diene)ruthenium(II),as a common compound, the synthetic route is as follows.
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%).
As the paragraph descriping shows that 50982-12-2 is playing an increasingly important role.
