And the article was included in Physical Chemistry Chemical Physics in 2013.Application In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:
The mixing states of imidazolium-based ionic liquid, 1-dodecyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide (C12mim+TFSA–), and two aryl solvents toluene and α,α,α-trifluorotoluene (TFT) were clarified on both meso- and microscopic scales using small-angle neutron scattering (SANS) and ATR-IR techniques. To elucidate the interactions between C12mim+TFSA– and aryl solvent mols. from the change in the electron densities of C12mim+ and TFSA–, 1-dimensional-NMR measurements for 1H and 13C atoms were conducted on C12mim+TFSA–-aryl solvent solutions as a function of the aryl solvent mole fraction. The interactions between the dodecyl chain of C12mim+ and aryl solvent mols. were observed using 2-dimensional-NMR techniques of 1H{1H} ROESY and 19F{1H} HOESY. These results were compared with those of benzene solutions previously studied. The SANS measurements showed that toluene is heterogeneously mixed with C12mim+TFSA– as well as benzene. However, the heterogeneity of the toluene solutions is slightly lower than that of the benzene solutions In contrast, TFT is homogeneously mixed with the ionic liquid at least on the present SANS scale. The substituent effects of the three aryl solvent mols. of benzene, toluene, and TFT on the mixing states of the solutions are discussed in terms of the cation-π interaction between the imidazolium and Ph rings and the interaction between the dodecyl group and aryl solvent mols. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Application In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide).
3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5) belongs to imidazole derivatives. Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Application In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide
