It is a common heterocyclic compound, the ruthenium-catalysts compound, Dichloro(cycloocta-1,5-diene)ruthenium(II), cas is 50982-12-2 its synthesis route is as follows.
Dichloro(1,5-cyclooctadiene)ruthenium (4.0 g, 0.014 moles), tricyclohexylphosphine (8.4 g, 0.030 moles), degassed triethylamine (2 mL), and degassed sec-butanol (60 mL) were combined in a pressure bottle under argon. The pressure bottle was purged with hydrogen gas, pressurized to 60 psi, and the mixture heated to 80 C. for 18 hours (the bottle was repressurized as needed to maintain 60 psi hydrogen). The reaction mixture was then allowed to cool down and the hydrogen gas was vented off. Degassed methanol (60 mL) was added to the orange slurry and the filtrate decanted off via stick filtration under argon to leave an orange solid in the bottle, which was washed with degassed methanol (60 mL). Degassed toluene (60 mL) was added to the orange solid and the orange slurry cooled to 0 C. Degassed 3-chloro-3-methyl-1-butyne (1.7 mL, 0.015 moles) was added dropwise via syringe at 0 C. The orange slurry progressively turned to a maroon slurry, while gas bubbled away. The mixture was stirred at room temperature for 2 hours after addition was complete. Ligand precursor [ 2] (18 g, 0.102 moles) was then charged and the mixture was heated to 80 C. and sparged with argon for 3 days (degassed toluene was added as needed). The brown slurry was allowed to cool to room temperature and a mixture of 30 mL methanol and 10 mL of concentrated hydrochloric acid was added in air with mixing. After stirring for 15 minutes at room temperature, the two phases were allowed to separate and the methanol phase was decanted off. Trituration with methanol (2¡Á50 mL) gave a solid, which was collected on a frit and washed with more methanol (2¡Á20 mL). The brown solid was then washed with hexanes (2¡Á20 mL) and dried to give [ 8] (5.1 g, 0.085 moles) in 61% yield.
