In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.246047-72-3, name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium An updated downstream synthesis route of 246047-72-3 as follows., 246047-72-3
A suspension of 218 mg (0.26 mmol) of [RuCl2(PCy3) (ImH2Mes)(phenylmethy- lene)], 26 mg (0.26 mmol) copper chloride and 49 mg (0.29 mmol) 2-methyl-8-vinyl- quinoline in 17 ml methylene chloride was stirred at 300C for 90 min. The reaction mixture was evaporated to dryness and the isolated crude product purified by silica gel chromatography (hexane / ethyl acetat 7:3) and finally digested in 15 ml hexane at room temperature for 30 min to yield 157 mg (96%) of the title compound as green crystals. MS: 632.9 (M+). 1H-NMR (300 MHz, C6D6): 2.15 (s, 3H); 2.29 (s, 6H); 2.64 (s, 12H); 3.49 (s, 4H); 6.30 (d, J=8.4Hz, IH); 6.80 (t, J=7.3Hz, IH); 6.98 (s, 4H); 7.10 (d, J=8.4Hz, IH); 7.40 (d, J=8.1Hz, IH); 7.52 (d, J=7.0Hz, IH), 17.15-17.32 (br, IH). Anal, calcd. for C32H35N3Cl2Ru: C, 60.66; H, 5.57; N, 6.63; Cl, 11.19. Found: C, 60.33; H, 5.58; N, 6.27; Cl, 10.90.
