2,6-二羟甲基对氯苯酚对F_4~(3+)具有较好的络合选择性,合成得到的相应冠醚既有好的络合性能又难溶于水,满足应用的要求。本文首先使用甲醚化的方法保护酚羟基,继而分别与三缩四乙二醇二对甲苯磺酸酯和四缩五乙二醇二对甲苯磺酸酯缩合生成相应的冠五和冠六,最后采用碘化锂去甲基得到含酚羟墓的冠五和冠六。红外光谱、元素分析、核磁共振、质谱的分析数据与结构相等。
2,6-dimethylol-p-chlorophenol has good complex selectivity to F_4 ~ (3+), and the corresponding crown ethers synthesized have good complex properties and are hardly soluble in water to meet the application requirements . In this paper, the first use of methyl ether method to protect the phenolic hydroxyl group, which were respectively and tetraglycol di-toluenesulfonate and tetrapentaethylene glycol di-toluenesulfonate condensation to produce the corresponding crown five and crown six, Finally, the use of lithium iodide demethylation to get the tomb of the crown of the five crown and six. Infrared spectroscopy, elemental analysis, nuclear magnetic resonance, mass spectrometry analysis of data and structure equal.
