The synthetic route is as follows., Application In Synthesis of 1-ethyl-2,3-dimethylimidazolium chloride
Example 181-Ethyl-2,3-dimethylimidazolium cyanodifluoropentafluoroethylborate-[C7H13N2][C2F5BF2(CN)] Potassium cyanodifluoropentafluoroethylborate K[C2F5BF2(CN)] (4.2 g, 18.0 mmol) is taken up in deionised water (2 ml), and a solution of 1-ethyl-2,3-dimethylimidazolium chloride [EDMIM]CI (3.2 g, 19.9 mmol) in 3 ml of deionised water is added. The ionic liquid obtained is washed with deionised water (4×2 ml), separated off and dried at 50 C. in vacuo. The yield of 1-ethyl-2,3-dimethylimidazolium cyanodifluoropentafluoroethylborate, which is liquid at room temperature, is 5.1 g (15.9 mmol), 88%, based on the potassium cyanodifluoropentafluoroethylborate K[C2F5BF2(CN)] employed. The product is analysed by means of ion chromatography and has low levels of contamination with halide; chloride: 7 ppm, bromide: 16 ppm, fluoride: 14 ppm. Water content (Karl Fischer titration): 161 ppm. Dynamic viscosity (20 C.): 47.2 mPa·s.Raman spectroscopy: v (CN)=2209 cm-1 1H-NMR: delta, ppm=7.60 d (CH, 1H), 3JH,H=2.15 Hz; 7.55 d (CH, 1H), 3JH,H=2.15 Hz; 4.32 q (CH2, 2H), 3JH,H=7.30 Hz; 3.90 s (CH3, 3H); 2.75 s (CH3, 3H); 1.46 t (CH3, 3H), 3JH,H=7.30 Hz.13C{1H}-NMR (cation): delta, ppm=145.32 s (Ctert, 1C); 123.30 s (CH, 1C); 121.19 s (CH, 1C); 44.20 s (CH2, 1C); 35.35 s (CH3, 1C); 15.07 s (CH3, 1C); 9.46 s (CH3, 1C).11B-NMR: delta, ppm=-2.7 tt (1B), 1JF,B=51.0 Hz, 2JF,B=25.3 Hz.19F-NMR: delta, ppm=-83.3 t (CF3, 3F), 4JF,F=5.2 Hz; -136.3 q (CF2, 2F), 2JF,B=23.3 Hz; -167.2 qq (BF2, 2F), 1JF,B=51.1 Hz, 4JF,F=5.1 HzElemental analysis: found, %, C, 37.57; H, 3.84; N, 13.10; calculated for C10H13BF7N3, %, C, 37.65; H, 4.11; N, 13.17.
