摘要
通过4′—甲酰基苯并—15—冠—5与二(邻氨基苯基)硫反应,合成了一种新的席夫碱型双冠醚.电导法测定的结果表明,该双冠醚与四苯基硼钠以1:1(冠醚单元:金属离子)形式配合,而与四苯基硼钾则以2:1形式配合,形成夹心式配合物.
A kind of Schiff base type bis(crown ethers)was prepared by thereaction of 4′-formylbenzo-15-crown-5 and di(o-aminophenyl)sulfer ether.Theresult of conductance measurement showed that the bis(crown ethers)formed 1:1(crown unit:metal ion)complex with sodium ion and formed 2:1 sandwichcomplex with potassium.
