八极分子2,4,6-三4-4-N-乙基-N-(2-羟乙基)氨基苯偶氮基苯乙烯基均三嗪的合成

摘要

以乙睛和乙醇为原料经2步反应合成了2,4,6-三甲基均三嗪(1);以对硝基甲苯和N-乙基苯胺为原料经3步反应合成了4-[4-[N-乙基-N-(2-羟乙基)]氨基苯偶氮基]苯甲醛(4);1与4在氢氧化钾的作用下经羟醛缩合合成了偶氮型八极分子2,4,6-三[4-[4-[N-乙基-N-(2-羟乙基)]氨基苯偶氮基]苯乙烯基]均三嗪,总产率27.09%,其结构经1H NMR表征.%2,4,6-Trimethyl-s-triazine(1) was prepared by a two-step reaction from acetonitrile and ethanol. 4- {4-[ N-ethyl-N-(2-hydroxyethyl) ] amino-phenylazo } benzaldehyde ( 4 ) was prepared by a three-step reaction from p-nitrotoluene and N-ethyl aniline. Octupolar molecules, 2,4,6-tris [ 4- [ 4-[ N-ethyl-N-(2-hydroxyethyl) ] amino-phenylazo ] styryl ] -s-triazine, was syhthesized by aldol condensation reaction of 1 and 4 in potassium hydroxide in total yield of 27.09％. The structures were characterized by 1H NMR.
