摘要
以[BMIM]BF4为介质,(Z)-4-苄基-2-甲基恶唑-5(4H)- 1与苯肼和(苯氨基甲基)苯在80-85℃下进行1-1.5 h的环保型一锅缩合反应,制得4-(苄基/取代苄基)- n -芳基氨基-2-(苯乙烯/取代苯乙烯)- 1h -咪唑-5(4H)- 1化合物,收率高。该方法的主要优点是反应时间短,易于处理,收率高。
[BMIM] BF4: An efficient ionic liquid medium for one-pot of 1H-Imidazole-5(4H)-one derivatives
The environment-friendly one-pot condensation reaction of (Z)-4-benzylidene-2-methyloxazol-5(4H)-one with phenylhydrazine and (phenyliminomethyl)benzene in the presence of [BMIM]BF4 as medium at 80-85 oC for 1-1.5 h to form 4-(benzylidene/substituted benzylidene)-N-aryl amino-2-(styryl/substituted styryl)-1H-imidazole-5(4H)-one compounds with good yields. The main advantages of this method are short reaction time, easy workup and good yields.
