Source of material
1-Ethylimidazole (9.61 g, 0.1 mol) was dissolved in methylbenzene (20 mL), 1,6-dibromohexane (12.1 g, 0.05 mol) was quickly added under stirring. The mixture was reacted at 80 °C for 10 min, and then heated to 90 °C for 8 hours. After the reaction completed (monitored by TLC), a white solid was produced after cooling. The resulting suspension was filtered, crushed and washed with ethylacetate and diethyl ether 3 times respectively. The white powder intermediate (C6EM—Br) was dryed in vacuo (19.32 g, yield 89%). Then the intermediates (C6EM—Br)(2.17 g, 0.005 mol), potassium hexafluoro phosphate (2.48 g, 0.012 mol) was dissolved in water (36 mL) and methanol (4 mL). The mixture stirred well for 12 h at 95 °C and then cooled slowly. The crystals suitable for X-ray analysis were obtained.
Experimental details
All H atoms were included in calculated positions and refined as riding atoms, with C—H = 0.90−0.97 Å with Uiso(H) = 1.5Ueq(C) for methyl H atoms and 1.2Ueq(C) for all other H atoms. The [PF6]− anion is disordered over two positions (cf. the figure, Table 2), which is typical for many hexafluoridophosphates.
Comment
Room temperature ionic liquid (RTIL) offer many advantages from an environmental perspective such as being nonflammable and thermally stable, having a negligible vapor pressure, and having the potential for recyclability. Dicationic ionic liquid, with a large variety of tunable interactions, has been explored in the past decade [3], [4], [5]. Because of the unique physical and chemical properties of ionic liquids, ionic liquids have the unique potential advantages of biodiesel preparation. In recent years, various functional ionic liquids have been synthesised, and have been used to prepare biodiesel highly efficiently and environmental friendly [6], [7]. It was found that dinuclear alkaline ionic liquid bis-(3-methyl-1-imidazolium-)ethlyene dihydroxide ([MC2]OH) shows excellent catalytic efficiency. The highest conversion rate of cotton seed oil was up to 98.5%, and the stability and separation effect of the catalyst was ideal [8].
Recently, our group focused on the preparation of biodiesel catalyzed by ionic liquid [9], [10] and reported three crystal structures of 1,1′-(butane-1,4-diyl)bis(3-methyl-1H-imidazol-3-ium), bis(hexafluorophosphate), 1,1′-(hexane-1,6-diyl)bis(3-methyl-1H-imidazol-3-ium), bis(hexafluorophosphate) and 1,1′-(ethane-1,2-diyl)bis(3-ethyl-1H-imidazol-3-ium), bis(hexafluorophosphate) [11], [12], [13]. In order to find the ionic liquid catalyst with better catalytic efficiency, we were engaged in synthesising novel ionic liquid catalysts with imidazole.
Herein, we report the synthesis and structure of the bisimidazoles ionic liquid. Bond lengths and angles within the imidazloe ring are very similar to those given in the literature for diimidazole ionic liquid [14]. The title structure consists of one half of C2M2+ cation (1,1′-(ethane-1,2-diyl)bis(3-ethyl-1H-imidazol-3-ium)) and one [PF6]− anion (cf. the figure). Two cationic 1-ethylimidazolium rings were bound to the both sides of ethyl group. The two imidazole rings are crystallographically dependant planar and parallel to each other. The torsion angle of C4—N1—C3—C2, C3—N1—C4—C5 and N1—C4—C5—C6 is 175.1(2)°, 156.7(2)° and 67.5(3)°, respectively.
