As a common heterocyclic compound, it belong ruthenium-catalysts compound,(1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium,246047-72-3,Molecular formula: C46H65Cl2N2PRu,mainly used in chemical industry, its synthesis route is as follows.,246047-72-3
A suspension of 1.50 g (1.77 mmol) of [RuCl2(PCy3)(ImH2Mes)(phenylmethylene)] (commercially available from Sigma- Aldrich Inc., St. Louis, USA), 0.19 g (1.94 mmol) of copper chloride and 0.51 g (1.94 mmol) of N,N-diethyl-2-[((E,Z)-2-propenyl)-phenoxy]- propionamide as a 4: 1 mixture of E/Z-isomers in 1 10 ml of dichloromethane was stirred for 40 min at 400C. The reaction mixture was evaporated to dryness at 400C/ 10 mbar. The crude title product was purified by repeated digestion with ethylacetate / pentane / tetrahydrofuran to yield 0.73 g (58%) of the title compound as a green crystalline solid.MS: 711.2 (M+). Anal, calcd. for C35H45Cl2N3O2Ru: C, 59.06; H, 6.37; N, 5.90; Cl, 9.96. Found: C, 58.56; H, 6.44; N, 5.23; Cl, 9.86.Crystals of the title compound suitable for X-ray crystal structure analysis were grown by vapor diffusion of pentane into a solution of 20 mg of [RuCl2(=CH(o- OCH(Me)CONEt2)Ph)(ImH2MeS)] in 2 ml of tetrahydrofuran at room temperature.
With the synthetic route has been constantly updated, we look forward to future research findings about (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium,belong ruthenium-catalysts compound
