摘要
从对叔丁基杯[4]芳烃出发,对其下沿的酚羟基进行修饰,先后在1,3-和2-酚羟基位点引入冠醚环和乙基;最后在NaH/THF中与3-溴丙烯酸丙酯反应制得聚合单体——新型杯[4]冠醚衍生物,其结构经1H NMR和MS表征。
A novel vinylic calix[4]crown monomer was synthesized from p-t-butylcalix[4]arene by introducing branched crown ether and ethyl at 1,3-and 2-posions of phenolic hydroxyl groups,then by the reaction of 5,7,11,23-tetra-t-butyl-25-hydroxy-27-ethyoxycalix[4]crown-5 with 3-bromopropyl acrylate in NaH/THF solution.The structure was characterized by 1H NMR and MS.
