  摘要：

  据报道，氯化铌（V）和几种咪唑鎓溴化物作为催化剂将环氧丙烷（PO）与二氧化碳环加成成碳酸亚丙酯（PC）。合成了31种不同的咪唑鎓溴化物，它们在所有5个咪唑鎓环原子上都有不同的取代基，其中17种以前从未报道过。研究了咪唑环上不同取代方式（空间和电子变化以及在PO中的溶解度）对催化活性的影响。催化剂结构的优化允许在温和的反应条件下以高的反应速率以非常好的收率和对PC的选择性来平衡二氧化碳的价位。

  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.

  N-烷基咪唑与烷基磺酸盐在室温下反应，有利于高产率地生成1,3-二烷基咪唑烷磺酸盐作为结晶固体。烷磺酸盐阴离子可以通过简单的阴离子、盐或酸反应在室温下在水中轻松被一系列其他阴离子[BF 4 , PF 6 , PF 3 (CF 2 CF 3 ) 3 , CF 3 SO 3 和(CF 3 SO 2 ) 2 N]所取代。用二氯甲烷萃取、过滤和溶剂蒸发，可以以80-95%的产率生产所需的离子液体。这些离子液体的纯度（在某些情况下>99.4%）是通过使用N-甲基咪唑基团的 13 C卫星信号强度作为内部标准来进行的。

  A chiral ionic compound comprising an alkyl substituted imidazolium or pyridinium cationic core having an alkyl ester side chain (-alkyl-C(O)O-) directly linked to the core and an associated counter anion, characterized in that the -O- atom of the ester side chain is linked to an alpha, a beta or a gamma hydroxycarboxylic acid functionality via the alpha, beta or gamma hydroxy of the acid functionality and the hydroxycarboxylic acid functionality has at least one asymmetric carbon, or characterized in that an -N= atom of the alkyl substituted imidazolium or pyridinium cationic core is substituted with an alpha, a beta or a gamma hydroxy group of a alpha, a beta or a gamma hydroxycarboxylic acid functionality and the hydroxycarboxylic acid functionality has at least one asymmetric carbon. The chiral ionic liquids (CILs) may be used as novel solvents, in particular for organic synthesis. The CILs have the potential to induce asymmetry into substrates or catalysts in a variety of organic transformations. A number of the compounds have low antimicrobial and low antifungal toxicities and are also biodegradable CILs.

  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.
