  Synthesis and Characterization of 5-Cyanotetrazolide-Based Ionic Liquids

  摘要：

  AbstractNew salts based on imidazolium, pyrrolidinium, phosphonium, guanidinium, and ammonium cations together with the 5‐cyanotetrazolide anion [C2N5]− are reported. Depending on the nature of cation–anion interactions, characterized by XRD, the ionic liquids (ILs) have a low viscosity and are liquid at room temperature or have higher melting temperatures. Thermogravimetric analysis, cyclic voltammetry, viscosimetry, and impedance spectroscopy display a thermal stability up to 230 °C, an electrochemical window of 4.5 V, a viscosity of 25 mPa s at 20 °C, and an ionic conductivity of 5.4 mS cm−1 at 20 °C for the IL 1‐butyl‐1‐methylpyrrolidinium 5‐cyanotetrazolide [BMPyr][C2N5]. On the basis of these results, the synthesized compounds are promising electrolytes for lithium‐ion batteries.

  The reaction of N-alkylimidazol with alkyl sulfonates, at room temperature, favors the production of 1,3-dialkylimidazolium alkane-sulfonates as crystalline solids at high yields. The alkane-sulfonate anions may be easily substituted by a series of other anions [BF 4 , PF 6 , PF 3 (CF 2 CF 3 ) 3 , CF 3 SO 3 and (CF 3 SO 2 ) 2 N] through simple anion, salt, or acid reactions in water at room temperature. The extraction with dichloromethane, filtration, and evaporation of the solvent, allows the production of the desired ionic liquids at a yield of 80-95%. The purity of these ionic liquids (in some cases >99.4%) is performed using the intensity of 13 C satellite signals from the magnetic resonance spectrums of the N-methyl imidazolium group as an internal standard.

  This invention relates to ionic liquid (ILs) solvents for chemical synthesis based on an alkyl - imidazolium cation core containing ionic liquids which have enhanced biodegradability and reduced toxicity relative to existing imidazolium bases ILs such as 1-butyl-3-methylimidazolium (bmmim) salts. Many of the described ILs produce a score of over 60% biodegradability over 28 days in a biodegradability test such as the Sturm Test, the Closed Bottle Test (OECD 301D) or the CO2 Headspace Test (ISO 14593). The ILs of the invention comprise an alkyl substituted imidazolium cationic core having a -C=OX- side chain in the 3-position of the imidazole ring, wherein X = O, NH, N or S and an associated counteranion characterized in that the -C=OX side chain comprises at least one ether linkage. The biodegradable and non-toxic IL may be used as green solvents for the chemical, pharmaceutical, biofuel and biomass industries. The ILs of the invention are particularly useful in hydrogenation, pericyclic and metathesis reactions.
