95% | 4.1-First Variant:Methyl trifluoromethanesulfonate (C. D. Beard et al; J. Org. Chem; 1973, 38, 3673) (4.26 g; 26.0 mmol) was added drop by drop, under stirring, into a cold solution (0 C.) of 2-butyl-imidazolium (3.10 g; 25.0 mmol) in 20 mL of dichloromethane. The resulting mixture was stirred for 30 minutes. 1 drop of water was added and shaken for one more hour. The reaction mixture was treated with anhydrous sodium carbonate and the resulting suspension was shaken for 30 minutes. Filtering followed by evaporation of the solvent produced the desired BMI.CF3SO3, a light yellow liquid (6.84 g; 95% yield). RMN-1H (CDCl3) delta: 9.03 (1H, s, C-H imidazolium); 7.48 (1H, s, C-H imidazolium); 7.47 (1H, s, C-H imidazolium); 5 4.21 (2H, t, J=7.3 Hz, NCH2); 3.97 (3H, s, NCH3); 1.87 (2H, quintet, J=7.3 Hz, CH2); 1.36 (2H, sextet, J=7.3 Hz, CH2); 0.91 (3H, t, J=7.3 Hz, CH3). |

75% | 4.2-Second Variant:1-Methyl-imidazolium (2.74 g; 33.3 mmol) was mixed together with n-butanol (2.47 g; 33.3 mmol) in 40 mL of dichloromethane and, under stirring and cooling in an ice bath, anhydrous sulfonic trifluoromethane (9.40 g; 33.3 mmol) was added drop by drop. After finishing the addition to the mixture, it was stirred for 1 hour at room temperature, to which a saturated aqueous solution of sodium carbonate (3.54 g; 33.3 mmol) was added. The solution was stirred for 30 minutes at room temperature. The phases were separated, with an organic dry phase that uses anhydrous sodium carbonate. The solvent was evaporated under vacuum and gently heated (50 C.), producing the desired BMI.CF3SO3 (7.19 g; 75% yield), identical to the material obtained in experiment 1.2.4.1 |

In acetone; at 20℃; for 24h; | General procedure: To a solution of the crude 1-butyl-3-methylimidazoliumbromide, obtained from the above reactions,in acetone (70 mL) was added hexafluorophosphoric acid (10.90 g,100.0 mmol). The reaction mixture was stirred for 24 h at room temperature. The resulting mixture was filtered. Evaporation of the solvent under reduced pressure afforded the corresponding 1-Butyl-3-methylimidazolium hexafluorophosphate. Same procedure was used except that trifluoro methane sulphonic acid (15.08 g,100.0 mmol) was used instead of hexafluorophosphoric acid. The resulting mixture was filtered. Evaporation of the solvent under reduced pressure afforded the corresponding imidazolium trifluromethanesulphonate.1-Butyl-3-methylimidazolium tetrafluoroborate was also prepared using the same procedure as above except that tetrafluoro boric acid (15.08 g, 100.0 mmol) was used in place of hexafluorophosphoric acid. Progress of the reaction was measured by TLC. Completion of the reaction was confirmed by 1HNMR. |

84% | In einen 2 I Schlenkkolben werden 620,5 g (5 mol) 1-Butylimidazol vorgelegt und 630,5g (5 mol) Dimethylsulfat portionsweise zugegeben. Der Ansatz wird danach 15 Minuten nachgeruehrt. Der Kolbeninhalt wird in ein 5I Becherglas ueberfuehrt und zu einer Mischung von 860,3g (5 mol) Natriumtrifluormethansulfonat in 2 Liter Wasser gegeben. Sofort bildet sich das Produkt als eine zweite fluessige Phase. Nach einer Phasentrennung wird die waessrige Phase noch einmal mit 1 Liter CH2Cl2extrahiert, und das organische Extrakt von Methylenchlorid befreit. Beide Produktfraktionen werden vereinigt und ueber Nacht bei 60C am HV getrocknet. Man erhaelt 1-Butyl-3-methylimidazolium-trifluormethylsulfonat in 84 %iger Ausbeute. Zum qualitativen Nachweis auf Chloridreste, werden ca. 1 g des Produktes in ca. 5 ml Wasser geloest und mit 2 Tropfen konzentrierter Salpetersaeure angesaeuert. Zu dieser Loesung werden dann ca. 3-4 Tropfen Silbernitrat gegeben um etwaig vorhandenes Chlorid als Silberchlorid auszufaellen. Das Ausbleiben eines Silberchlorid-Niederschlags spricht fuer die komplette Abwesenheit von Halogenidionen. 1H-NMR (300 MHz, Aceton-d3):0,87 (3 H, tr, J=9,2 Hz, Hh); 1,29-1,38 (2 H, m, Hg); 1,90-2,00 (2 H, m, Hf); 4,04 (3 H, s, Hb); 4,35 (2 H, tr, J=9,3 Hz, He); 7,71;7,78 (je 1 H, s, Hc,d); 9,11 (1 H, s, Ha) ppm. |

93% | With potassium trifluoromethansulfonate; In acetone; for 24h; | 65 g of 1-butyl-3-methylimidazolium trifluoromethanesulfonate was added to 150 ml of acetone, and 70 g (1.1 eq. ) of potassium TRIFLUOROMETHANESULFONATE was added thereto and reacted for 24 hours, followed by filtering the reactant solution to remove salts. The resulting filtrate was DISTILLED TO REMOVE ACETONE, GIVING AN UNPURIFIED 1-BUTYL-3-METHYLIMIDAZOLIUM TRIFIUOROMETHANESUIFONATE ionic liquid. To the unpurified 1-butyl-3-methylimidazolium trifluoromethanesulfonate ionic liquid was added ionic water to prepare a product having a concentration of about 50%, followed by transferring to a reflux device of the continuous distillation extraction apparatus. Then, methylene chloride was added to A RECEIVER (3V/W) AND REFLUXED AT 39 No. 40C FOR ABOUT 36 HOURS. THEN, THE methylene chloride solution was COLLECTED FROM THE RECEIVER OF THE CONTINUOUS distillation extraction apparatus and methylene chloride was distilled to be removed, followed by drying under reduced pressure at 60 C for 76 hours to remove water, thereby acquiring 1-BUTYL-3-METHYLIMIDAZOLIUM TRIFLUOROMETHANESULFONATE IONIC LIQUID. Yield : 100 g (93%), residual chloride ions: 2 ~ 20 ppm (before purification: 3,500 ppm), residual potassium ions: 1 ~ 5 ppm (before purification: 300 ppm), water: 300 ppm. To achieve high purity ionic liquids, the obtained 1-BUTYL-3- METHYLIMIDAZOLIUM TRIFLUOROMETHANESULFONATE ionic liquid was repeatedly purified. Yield : 95 g (95%), residual chloride ions: 1-5 ppm (before repeated cycles of purification: 2-20 ppm), residual potassium ions < 3 ppm (before repeated cycles of purification: 1 No. 5 ppm), water: 300 ppm. |

90% | With sodium O,O-diethyl phosphorodithioate; In tetrahydrofuran; mineral oil; at 20℃; for 4h;Inert atmosphere; | General procedure: To a solution of Baylis-Hillman adduct 1 (5 mmol) in dry THF (4 mL) was added IBX (5 mmol) and stirred at rt for 5 h to get alpha,beta-unsaturated aldehyde 3. Then, to a solution of O,O-diethyl hydrogen phosphorodithioate 2 (5 mmol) in dry THF (5 mL) was added dropwise a suspension of NaH (10 mmol) in dry THF (20 mL) with stirring to rt. After the addition was complete and evolution of hydrogen gas (effervescence) had ceased, the reaction mixture was stirred at 60 C for 30 min and then cooled to rt. In this solution was added alpha,beta-unsaturated aldehyde 3 followed by [bmim]X-Y (5 mmol) and the reaction mixture was stirred at rt for 2-4 h. Water (30 mL) was added, the mixture was extracted with ether (3×30 mL), the combined organic layers were dried over anhydrous sodium sulfate, filtered and evaporated under reduced pressure. The crude product thus obtained was purified by silica gel column chromatography (hexane/EtOAc, 95:5) to afford an analytically pure sample of 6. |

1.382 g | In neat (no solvent); at 100℃; for 0.333333h;Microwave irradiation; | General procedure: a mixture of 1-methylimidazole (0.4105 g, 5 mmol), 1-bromobutane (0.6850 g, 5 mmol) was heated under microwave irradiation (or conventional heating) in a 10 mL pressurized glass tube fitted with a Teflon-coated septum at 80 C for 20 min. Then, LiOTf (0.78 g, 5 mmol) was added and the mixture was irradiated at 100 C for 20 min. After cooling, the mixture was diluted with MeCN (5 mL), and after removal of the precipitated salt LiBr, the filtrate was then filtered through Celite. The crude product was washed with Et2O and concentrated to give a colorless to pale yellow liquid (1.382 g, 96 % yield). The [BMIM]OTf was dried under reduced pressure. The purity and authenticity of the ionic liquids were confirmed by 1H and 13C NMR spectroscopy. |
In acetone; acetonitrile; at 60℃; for 24h; | 1-Butyl-3-methylimidazolium bromide was dissolved in acetone/acetonitrile (50:50) and an equimolar amount of LiTfO in acetone was added. The mixture was stirred for 1 day at 60 C and then filtered. The solvent was removed under reduced pressure and the crude product dissolved in CH2Cl2. Upon cooling to 5 C most of the Li halide precipitated and the precipitate was filtered off. The remaining solution was washed halide-free with deionized water (AgNO3 test) and filtered over a column filled with neutral Al2O3 and activated charcoal. The residual organic phase was freed from solvent under reduced pressure and dried under dynamic vacuum for 1-2 days at 80-90 C. |
