摘　　要：用2,3-二氯喹(口恶)啉分别与4′-氨基苯并-12-冠-4、4′-氨基苯并-15-冠-5和4′-氨基苯并-18-冠-6作用合成了三种用喹(口恶)啉环桥联的双冠醚。电导研究表明,可分别与 Na^+、K^+、Rb^+和 Cs^+形成2:1[冠醚单元:金属离子]的配合物。求出了三种双冠醚在氯仿中的萃取平衡常数和萃取分配比。Three kinds of bis-crown ethers containingquinoxaline ring were synthesized by the reactionof 4'-aminobenzo-12-crown-4,4'-aminobenzo-15-crown-5 and 4'-aminobenzo-18-crown-6 with2,3-dichloroquinoxaline respectively.Conductancestudies showed that these bis-crown ethers form2:1(crown ether units:metal ion)complexes withsodium,potassium,rubidium and cesium saltsrespectively.The ratio of distribution and theextraction equilibrium constants of the title com-pounds with these salts in chloroform have beenevaluated.
