离子液体中安替比林色酮Schiff碱的合成

Synthesis of Aminoantipyrine Chromones Schiff Base in Ionic Liquid

在离子液体中，4-氨基安替比林和取代-3-甲酰基色酮反应，合成了4种含色酮环的Schiff碱（其中2种为新化合物），收率77％-94％，其结构经^1H NMR和IR表征。

Four Schiff base of aminoantipyrine chromones（3a -3d） in yields of 77% -94% were synthesized by the reactions of 4-aminoantipyrine with substituted-3-formylchromone in ionic liquid. Their structures were confirmed by ^1H NMR and IR. 3b and 3d were new compounds.
