摘要:本文主要研究了在常压温和无碱条件下,以三苯胺醛基为起始原料, 在Se/CO/H2O/DMF体系下,用计量的硒原位产生的硒化氢合成了对称的三苯胺二硒醚。考察了硒用量、反应温度、水量、溶剂的选择等反应条件对产率的影响,得出最佳反应条件为:硒与三苯胺醛摩尔比4:1,溶剂为N, N-二甲基甲酰胺,水用量为2ml,反应温度为90~95℃,在此条件下最佳产率为85%。同时还探讨了三苯胺二硒醚的形成机理。18843 毕业论文关键词:二硒醚;三苯胺;还原硒化;合成
The synthesis of diselenide containing triphenylamine
Abstract: In this paper,the selenium measurement generated in situ synthesis of hydrogen selenide symmetric triphenylamine diselenide was systematically investigated using triphenylamine aldehyde as raw material under Se/CO/H2O/DMF system without any base at atmospheric pressure.The effects of the amount of selenium,reaction temperature,the amount of water,the selection of solvent on the yield were investigated.And the optimum reaction conditions were:the molar ratio of selenium/triphenylamine aldehyde of 4:1,the solvent of N, N- dimethylformamide,the desired amount of water of 2 ml,the reaction temperature of 90 ~ 95 ℃, the yield was 85% at optimum reaction condition.At the same time,the triphenylamine diselenide formation mechanism was proposed.
