基于4,4-联吡啶手性离子液体的合成及表征

Synthesis and Charaterization of Chiral Iconic Liquids Based on 4,4-Dipyridine

离子液体作为一种新型的绿色溶剂和催化剂已引起了化学家们的极大关注。以4,4′-联吡啶、(-)-薄荷醇及溴乙酰溴为起始原料合成两种手性离子液体并进行红外、氢谱和碳谱结构表征。然后分别与四氟硼酸钠和六氟磷酸钾进行阴离子交换得到相应的手性离子液体。

In recent years,ionic liquid as one kind of new green solvent and catalyst has aroused enormous interest. In this paper,chiral （-）-N,N’- dimenthyl-4,4’-dipyridinecarboxylate bromonium ionic liquids was synthesized from L-menthol,4,4-bipyridine,and bromine acetyl bromide as starting materials,and characterized by IR,1H NMR,13C NMR. In addition,this chiral bromonium ionic liquids was exchanged with sodium tetrafluoroborate and hexafluorophosphate anion respectly to get corresponding ionic liquids with different anion.
