A common heterocyclic compound, the ruthenium-catalysts compound, name is (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride,cas is 301224-40-8, mainly used in chemical industry, its synthesis route is as follows.
General procedure: Hoveyda-Grubbs 2nd generation catalyst (19mg; 0.03mmol) was added to a solution of dien 7 (100mg; 0.31mmol) and styrene (2.48mmol) in dichloroethane (5mL). The reaction mixture was heated at 80C for 5h. Then, another portion of H-G catalyst (19mg; 0.03mmol) was added and the reaction mixture was heated at 80C for additional 5h. Then, the solvent was evaporated and crude solid was purified by column chromatography on silica gel (mobile phase – 3% ethyl acetate in cyclohexane, Rf of products 0.18-0.25). In some cases, stated in each experiment, HPLC had to be used due to very close retention time of product and starting material (mobile phase – 0.5% ethyl acetate in cyclohexane).
As the rapid development of chemical substances, we look forward to future research findings about 301224-40-8
