Catalytic asymmetric cycloaddition of CO2 to epoxides via chiral bifunctional ionic liquids was written by Duan, Shuhui;Jing, Xinyao;Li, Dandan;Jing, Huanwang. And the article was included in Journal of Molecular Catalysis A: Chemical in 2016.Synthetic Route of C11H20N2 This article mentions the following:
A series of new chiral ionic liquid catalysts composed of the N,N’-bis(salicyclidene) cyclohexene diaminatocobalt and an imidazolium salt were designed, prepared and applied for the chiral cyclic carbonate synthesis from racemic epoxides and carbon dioxide. All reactions exhibit good enantioselectivity for the chiral cyclic carbonate without polycarbonate and other byproducts. The order of The order of catalytic activity toward the axial anions is OAc– > CF3CO–2 > CCl3CO–2 > OTs– and the order of enantioselectivity is OTs– > OAc– > CCl3CO–2 > CF3CO–2. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Synthetic Route of C11H20N2).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Synthetic Route of C11H20N2
