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.
A suspension of 790 mg (0.93 mmol) of [RuCl2(PCy3) (ImH2Mes)(phenylmethy- lene)], 95 mg (0.96 mmol) copper chloride and 196 mg (1.03 mmol) 4-chloro-8-vinyl- quinoline in 70 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 5:2) and finally digested in 20 ml pentane at room temperature for 30 min to yield 311 mg (51%) of the title compound as green crystals. MS: 655.0 (M+). 1H-NMR (300 MHz, CD2Cl2): 2.35 (s, 6H); 2.39 (s, 12H); 4.04 (s, 4H); 7.00 (s, 4H); 7.25 (d, J=5.3Hz, IH); 7.43 (dd, J=8.2, 7.3Hz, IH); 7.56 (dd, J=7.1, 0.7Hz, IH); 8.13 (d, J=5.3Hz, IH); 8.41 (dd, J=8.2, 0.7Hz, IH); 16.95 (s, IH). Anal, calcd. for C31H32N3Cl3Ru: C, 56.93; H, 4.93; N, 6.42; Cl, 16.26. Found: C, 56.59; H, 5.04; N, 6.02; Cl, 15.49.
246047-72-3, The synthetic route of 246047-72-3 has been constantly updated, and we look forward to future research findings.
