As a common heterocyclic compound, it belongs to ruthenium-catalysts compound, name is Dichloro(cycloocta-1,5-diene)ruthenium(II), and cas is 50982-12-2, its synthesis route is as follows.
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%).
50982-12-2, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,50982-12-2 ,Dichloro(cycloocta-1,5-diene)ruthenium(II), other downstream synthetic routes, hurry up and to see
