With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.246047-72-3,(1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium,as a common compound, the synthetic route is as follows.
Complex 1 (2.0 grams) was dissolved in toluene (10 mL), and 4-phenylpyridine (1.50 grams, 4 mol equivalents) was added. The reaction flask was purged with argon and the reaction mixture was stirred for approximately 12 hours at about 20 C. to about 25 C. during which time a color change from dark purple to dark green was observed. The reaction mixture was transferred into 75 mL of cold (about 0 C.) pentane, and a dark green solid precipitated. The precipitate was filtered, washed with 420 mL of cold pentane, and dried under vacuum to afford (IMesH2)(C11H9N)2(Cl)2Ru-CHPh 13 as a dark green powder (2.0 grams, 97% yield). [00135] 1H NMR (500 MHz, CD2Cl2): d19.23 (s, 1H, CHPh), 8.74 (br. s, 2H, pyridine), 7.91 (br. s, 2H, pyridine), 7.70-7.08 (multiple peaks, 19H, ortho CH, para CH, meta CH, pyridine), 6.93 (br. S, 2H, Mes CH) 6.79 (br. s, 2H, Mes CH), 4.05 (br. s, 4H, NCH2CH2N), 2.62-2.29 (multiple peaks, 18H, Mes CH3).
246047-72-3, 246047-72-3 (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium 11147261, aruthenium-catalysts compound, is more and more widely used in various fields.
