Imidazolium-type room temperature ionic liquids (RTILs) have been used for the Stetter reaction, affording the desired 1,4-dicarbonyl compounds in good yields. Thiazolium salts and Et3N are efficient catalysts for this reaction performed in ionic liquid. The possibility to recycle and reuse the solvent has been demonstrated, although it was not possible to recycle the thiazolium catalyst. This method
咪唑型室温离子液体(RTIL)已用于Stetter反应,以良好的收率提供了所需的1,4-二羰基化合物。噻唑鎓盐和Et 3 N是在离子液体中进行该反应的有效催化剂。已经证明了再循环和再利用溶剂的可能性,尽管不可能再循环噻唑鎓催化剂。该方法用于氟哌啶醇的全合成。
