Dichloro(cycloocta-1,5-diene)ruthenium(II), cas is 50982-12-2, it is a common heterocyclic compound, the ruthenium-catalysts compound, its synthesis route is as follows.
b) A brown suspension of RuCl2(1,5-cyclooctadiene) (560 mg; 2 mmol), 0.6 ml of 1,8-diazobicyclo[5.4.0]undec-7-ene (DBU) and 1.18 g of tricyclohexylphosphine in 60 ml of isopropanol was stirred at 80 C. for 2 hours. 60 ml of toluene was added to the resulting brick-red suspension and the mixture was stirred at 80 C. for a further 90 minutes and cooled to -10 C. After addition of 0.55 ml of trimethylsilylacetylene, 10 ml of 2 M HCl solution in diethyl ether were added and the mixture was subsequently stirred for 5 minutes. The mixture was warmed while stirring to 0 C. and stirred for 45 minutes. After evaporation at 0 C. in a high vacuum, the residue was stirred with cold MeOH. The resulting violet powder was washed with cold methanol and dried under reduced pressure. Yield 1.40 g (92%).
As the rapid development of chemical substances, we look forward to future research findings about 50982-12-2
