General procedure: The following common procedure was followed for the synthesesof complexes 1-5: A mixture of the ligand (0.36 mmol) and Ru(1,5-cod)Cl2(0.36 mmol) was dissolved in dry ethanol (10 ml) and the resultingmixture was refluxed for 2 h. The reaction volume was concentratedto a third of its original volume and the suspension was keptat 4 C overnight to give brick red solid which was filtered off,washed with cold ethanol and then diethyl ether. The solid wasdissolved in chloroform and excess of n-hexane was added toinduce the precipitation of the brick red solid product.

The chemical industry reduces the impact on the environment during synthesis,50982-12-2,Dichloro(cycloocta-1,5-diene)ruthenium(II),I believe this compound will play a more active role in future production and life.

The catalyst precursor, preferably [RuCI2(COD)]m (1 eq.), 1 ,4-bis(diphenylphosphino)butane (1 .0-1 .2 eq., preferably 1 .0 eq.) and 2- quinolinylmethylamine (1.0-1 .4 eq., preferably 1.225 eq.) were dissolved in one of the above mentioned solvents, preferably cyclohexanone (10- 20 ml/g Ru-precursor, preferably 20 ml/g). The mixture was heated at 130 C for 1 hour and then cooled to ambient temperature. The solid precipitate was filtered off and washed with the same solvent that was used for the reaction. A person skilled in the art can determine the cis-/trans- isomeric ratio by NMR. The diastereomeric ratios generated by this method are usually in the range of d.r. (diastereomeric ratio) >98% towards the cis isomer. The same results can be achieved starting with [RuCI2(dmso-KS)3(dmso-KO)], [RuCI2(dmso-KS)4]or [RuCI2(bicyclo[2.2.1]hepta-2,5-diene)]m as precursor

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.

Next, 31.56 g of this (eta-1,5-cyclooctadiene)ruthenium(II) dichloride, 34.97 g of sodium carbonate, 28 mL of 2,4-pentanedione and 100 mL of N,N-dimethylformamide were placed in a nitrogen-flushed three-neck flask and stirred at 140 C. for 1 hour. Following reaction completion, the solution was cooled to room temperature, then alumina column chromatography (developing solvent: diethyl ether) was carried out. The resulting solution was concentrated, after which 120 mL of water was added and the solution was left at rest for 3 hours. The crystals that precipitated out were collected by filtration, and after being washed with water, were dried in vacuo. 46.53 g of bis(2,4-pentanedionato)(eta-1,5-cyclooctadiene)ruthenium(II) was obtained as an orangey-yellow solid. The yield was 94 wt %.

In a glovebox complex 16 (0.125 g, 0.200 mmol) was dissolved in dichloromethane (3 ml), resulting in a darkgreen solution. AgOCN (149.89 g/mol, 0.460 mmol, 0.0689 g, 2.3 eq.) was suspended in DMF (2 ml) and slowly added.The reaction mixture was stirred for 3.5 h at room temperature before it was filtered and the resulting brown-greensolution dried in vacuum. The residual was dissolved in toluene and the resulting solution was filtered and dried invacuum to give complex 17 as a brown foam (125 mg, yield = 98 %). 1 H NMR (400.13 MHz, C6D6): delta = 16.65 (s, 1 H),7.06 (d, J = 7.4, 2 H), 6.86 (s, 4 H), 6.67 (t, J = 7.4, 1 H), 6.22 (d, J = 8.3, 1 H), 6.12 (s, 2 H), 4.25 (sep, J = 6.1, 1 H),2.23 (s, 12 H), 1.86 (s, 6 H), 1.07 (d, J = 6.1, 6 H).

EXAMPLE 1 Metathesis by Ethenolysis of Methyl Oleate Catalyzed by a Type 3 Complex (FIG. 1) in an Ionic Liquid; 1 ml of 3-butyl-1,2-dimethylimidazolium bis-triflylamide with formula [BMMI]+[N(CF3SO2)2]- pre-dried overnight at 80 C., 148 mg of methyl oleate (source: Fluka, with a purity higher than 98%) and 15 mg of the complex with formula Cl2Ru(CH-o-O-iPrC6H4)PCy3 (synthesized by reacting the 1st generation Grubbs complex with formula Cl2Ru(CHC6H5)(PCy3)2 with 1-isopropoxy-2-vinylbenzene in the presence of CuCl), this corresponding to 5% molar of catalyst with respect to methyl oleate, were introduced, in an inert atmosphere of argon, into an autoclave reactor provided with an agitation system and a pressure sensor. The autoclave was then placed under vacuum and pressurized to obtain a pressure of 10 bars (1 MPa) of ethylene (origin: Alphagas, quality N25). The temperature was kept constant at 20 C. The medium was stirred at ambient temperature for 2 hours, then the excess ethylene was slowly purged by returning to atmosphere pressure at a temperature not exceeding 20 C. and the autoclave was again placed under an atmosphere of argon. The products were separated from the ionic liquid by adding 2 to 3 ml of heptane distilled over CaH2 and degassed. An aliquot (100 mul) of the extracted solution was passed through a short silica column (2 cm) eluted with diethyl ether. It was analyzed by gas phase chromatography (ZB-1 column, 100% dimethylpolysiloxane, 30 metres, helium vector gas 2 ml/min, temperature programming: 60 C. then 5 C./min to 220 C.) coupled to a mass spectrometer. The methyl oleate conversion was 95%. It was calculated using decane as an internal reference. The reaction products were composed of 1-decene (fraction A) and methyl decenoate (fraction B). The presence of 1-decene isomers was not detected. Homo-metathesis products were present in trace amounts and could not be quantified.

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium, 172222-30-9
