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 1.00 g (1.19 mmol) of [RuCl2(PCy3)(ImH2Mes)(phenylmethylene)] (commercially available from Sigma- Aldrich Inc., St. Louis, USA), 0.15 g (1.47 mmol) of copper chloride and 0.30 g (1.47 mmol) of 2-[((?,Z)-2-propenyl)-phenoxy]-propionarnide as a 3.5:1 mixture of E/Z-isomers in 75 ml of dichloromethane was stirred for 30 min at 400C. The reaction mixture was evaporated to dryness at 40C/10 mbar. The crude title product was dissolved in 100 ml of ethyl acetate and the formed suspension filtered. The filtrate was evaporated to dryness at 40 C/10 mbar. The crude title product was purified by repeated digestion with pentane / THF to yield 0.41 g (53%) of the title compound as a green solid.MS: 655.1 (M+). Anal, calcd. for C3IH37Cl2N3O2Ru: C, 56.79; H, 5.69; N, 6.41; Cl, 10.81. Found: C, 56.23; H, 5.59; N, 6.16; Cl, 10.84.Crystals of the title compound suitable for X-ray crystal structure analysis were grown by vapor diffusion of pentane into a solution of 10 mg of [RuCl2(=CH(o-OCH(Me)CONH2) Ph)(ImH2MeS)] in 0.5 ml of tetrahydrofuran at room temperature.Fig. 3 shows a labeled view of the complex of formula E.
246047-72-3, The synthetic route of 246047-72-3 has been constantly updated, and we look forward to future research findings.
