246047-72-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, cas is 246047-72-3,the ruthenium-catalysts compound, it is a common compound, a new synthetic route is introduced below.
To a Schlenk flask charged with Grubbs? catalyst 2 (0.42g, 0.50mmol) and CuCl (0.05g, 0.50mmol), compound 9 (0.6mmol) in 10mL dry dichloromethane was added at room temperature under N2. The resulting mixture was stirred for 40min at 40C. After being cooled to room temperature, the reaction mixture was filtered and the clear filtrate was collected. The solvent from the filtrate was evaporated under vacuum to give a residue. The residue was purified by silica gel chromatography (CH2Cl2: ethyl acetate=2:1 or pentanes: ethyl acetate=3:2 or1:1) to give the desired product as a green crystalline solid. Yield: 65.7%. Anal. Calc. for C34H43Cl2N3O2Ru: C, 58.53; H, 6.21; N, 6.02. Found: C, 58.45; H, 6.21; N, 5.95%. 1H NMR (400MHz, CDCl3) delta (ppm): 1.41 (d, J=6.3Hz, 3H), 2.38 (s, 3H), 2.40 (bs, 6H), 2.52 (bs, 12H), 2.77 (s, 3H), 2.79 (s, 3H), 4.10 (s, 4H), 5.23 (q, J=6.6, 1H), 6.54 (d, J=8.3Hz, 1H), 6.75 (s, 4H), 7.08 (s, 4H), 7.28 (d, J=8.4Hz, 1H), 16.37 (s, 1H). 13C NMR (100MHz, CDCl3) delta: 16.7, 21.4, 27.3, 36.2, 37.0, 51.9, 62.2, 73.4, 112.3, 129.4, 129.3, 129.6, 133.2, 138.3, 145.9, 149.4, 171.4, 210.5, 302.1ppm.
