摘要
由N,N-二甲基丙二胺和对叔丁基杯[n]芳烃乙酸酯化合物2a^2c(n为4、6、8)直接酰胺化反应合成了含有叔胺端基的杯芳烃酰胺衍生物3a^3c(n为4、6、8),产物的结构是具有章鱼状的多足杯芳烃主体,对金属离子具有较好的选择性萃取性能。3a和3c可以分别选择性萃取碱金属离子Na+和K+。
Three N, N-dimethylpropyl tert-butylcalix [ n ] aryl acetoamides 3a - 3c （ n = 4, 6, 8 ） were synthesized in moderate yields by treating ethyl tert-butylcalix[ n] aryl acetates with N,N-dimethyl-1,3-diaminopropane, which were prepared by the alkylation of tert-butyicalix [ n] arenes with ethyl chloroacetate in a system of K2CO3/KI/acetone. The extraction properties of these polydentated amide derivatives with octopus shape for metal cations were tested. Compounds 3a and 3c show especiaUy selective extraction for Na^＋ and K^＋ respectively.
