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.,50982-12-2

Complex C-l was also prepared using [RuCl2(COD)]n as a precursor. Thus, a mixture of [RuCl2(COD)]n (309 mg, 1.103 mmol), PPh3 (289 mg, 1.103 mmol) and ligand Id (248 mg, 1.103 mmol) was stirred in toluene (10 ml) at 115C for 24 h in a KONTES pressure tube. After cooling, the resulting brick colored precipitate was filtered on a filter frit, washed with diethyl ether (3 x 10 ml) and vacuum dried to afford 494 mg of a light pink crude material (Found C, 53.43; H, 5.26; N, 4.08%). Recrystallization from hot THF, filtering and layering with diethyl ether, afforded burgundy crystals (261 mg, 32% yield as a THF solvate). Based on NMR analysis, these crystals represent a THF solvate of complex C-l. The crystals were found to lose solvent based on elemental analysis. Elem.

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.

Example 2; Synthesis of the Alkylidene Complex (2): Ru(cod)Cl2 (660 mg, 2.35 mmol) was suspended in iPrOH (20 ml) under an Ar atmosphere. DBU (0.75 ml) and PCy3 solution (c=20%, 0.77 M in toluene, 7.7 ml) was added. The brown suspension obtained was stirred at 80 C. for 1 hour and toluene (25 ml) was then added. The mixture was stirred at 80 C. for a further 30 minutes. The reaction mixture was then cooled to 0 C. and 1-trimethylsilyl-1-hexyne (2.1 g) was added. After stirring for 10 minutes, HCl solution (c=2 M in Et2O, 2.4 ml) was added to the reaction mixture at 0 C. After stirring for 1 hour, the reaction mixture was evaporated. MeOH (about 30 ml) was added to the residue. Filtration gave the complex 2. The NMR also shows by-products.NMR in CDCl3 delta 31P 35.81 ppm. 1H delta 20.01 ppm.

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%.

The same compound is obtained if the synthesis is carried out in the presence of P(C6F5)3. (0457) [0216] An X-ray structure of complex K-1 revealed that one ligand coordinates to one Ru atom via mer-fashion. A second ligand coordinates to second Ru atom via ^ac-fashion. Both Ru atoms are connected via one bridging CI atom. One S(Ph) atom is part of mer-coordinated la. There appears to be a hydrogen-bonding interaction between one NH group of the fac- coordinated ligand and terminal CI atom attached to the first Ru atom. Complex K-1 exists as a single species in solution. The NH hydrogen atom H-bonded to the chloride ligand appears at delta 9.19 ppm in the 1H NMR spectrum. It is shifted to low field by Deltadelta = 4.47 ppm relative to the NH resonance of the non-H bonded NH group.
