• Recyclable montmorillonite-supported thiazolium ionic liquids for high-yielding and solvent-free upgrading of furfural and 5-hydroxymethylfurfural to C₁₀ and C₁₂ furoins

  Six Na+/montmorillonite (MMT) – supported thiazolium (TM) ionic liquids (ILs), MMT–[TM], which are precatalysts to N-heterocyclic carbene (NHC) catalysts, have been synthesized and employed to catalyze the highly selective condensation of furfural (FF) and 5-hydroxymethylfurfural (HMF) into C10 and C12 furoins, respectively. Among them, five supported [TM] salts carrying the electron-donating group

  已合成了六种Na + /蒙脱土（MMT）负载的噻唑（TM）离​​子液体（ILs）MMT–TM，它们是N杂环卡宾（NHC）催化剂的预催化剂，并用于催化高度选择性的缩合将糠醛（FF）和5-羟甲基糠醛（HMF）分别转化为C 10和C 12糠醛。其中，带有电子给体基团的五种负载的TM盐表现出优异的催化活性。因此，通过用Et 3 N活化MMT-TM原位生成的负载型NHC催化剂可提供C 10和C 12呋喃素的产率分别为97–99％和97–98％。该缩合反应也可以在无溶剂的条件下进行，并且催化剂可以容易地再循环，在四个连续的循环中没有显示出催化活性的明显损失。因此，当前催化剂体系所具有的这些期望的特征使得能够开发用于FF和HMF的升级的更绿色和更环境友好的方法。
