  咪唑鎓离子液体在有机溶剂中电生成的N-杂环卡宾的稳定性和有机催化效率

  摘要：

  在有机溶剂中，通过母体1-丁基-3-甲基咪唑鎓盐BMIm-X的阴极还原，在有机溶剂中生成1-丁基-3-甲基咪唑-2-亚烷基（选择为N型杂环卡宾-NHC模型）的动力学，通过简单的伏安分析进行了研究。研究了NHC降解速率对有机催化反应效率的影响（由肉桂醛和三氟甲基苯乙酮合成γ-丁内酯）。溶剂和阴离子X的性质-对NHC的稳定性的显着效果，二（三氟甲基磺酰）亚胺阴离子为最佳长期持久的卡宾（而乙腈似乎是最糟糕的溶剂）。X的作用-已涉及到NHC和X之间的竞争-，在与BMIm +的氢键相互作用中。NHC通过氢键的稳定性越高，其降解速率越低。先前在纯BMIm-X中报道的这些氢键相互作用似乎甚至在低浓度（c <0.1 mol L -1）包含BMIm-X的有机溶剂中也有效。还指出了氮烷基取代基对NHC降解的影响（并因此对其作为有机催化剂的效率）的影响。

  have a remarkable effect on the stability of the NHC, the bis(trifluoromethylsulfonyl) imide anion being the best for a long lasting carbene (while acetonitrile seems to be the worst solvent). The role of X− has been related to a competition between NHC and X−, in the hydrogen bonding interaction with BMIm+. The higher the stabilization of NHC by hydrogen bond, the lower its degradation rate. These
