摘要: 双冠醚与较大的金属离子能形成夹心型络合物,与相应的单冠醚相比较,它们具有更好的络合性和选择性。但双冠醚一般不溶于水中。本文用EDTA二酐与4'-氨基苯并-12-冠-4及4'-氨基苯并-15-冠-5反应,制得了两种在桥键上带有两个羧基的酰胺型双冠醚Ⅰ和Ⅱ。Ⅰ、Ⅱ未见报导,均能溶于水,这就可以象其它水溶性单冠醚一样,在水溶液中研究它们的络合行为。

Abstract: This paper discribes the synthesis of amide-type bisbenzocrown ethers bearing two carboxymethyl groups on the briged chain. That is, two N, N'-bis(4'-aceta-midobenzocrown ethers) ethylenediamine-N,N'-diacetic acid were obtained by the reaction of EDTAdianhycride with 4'-aminobenzo-12-crown-4 or 4'-aminobenzo-15-crown-5.
