摘 要:希肤碱是一种稳定的亚胺,在工业和生物学方面有很大的价值和作用,目前合成希肤碱的方法有很多,我们发现在Se/CO/H2O的体系中,以硝基苯、苯甲醛醛为原料,以DMF为溶剂,在常压下,温度为95℃下搅拌12小时,然后在空气中,进行搅拌、过滤,提纯既得到席夫碱。这个反应为锅反应而且在常压下进行,反应条件温和,操作简单、安全,成本低,反应选择性高且产率也高。这是合成席夫碱的一种新方法。28283

Nitrobenzene And Benzaldehyde-Pan to Praparation of Schiff’s Base Reaction
Abstract:Schiff base is a stable imine,it hase a great application in industry and biology and value.At present,there are many synthesis of Schiff’s base,we find in the presence of Se/CO/H2O catalysis system,nitrobenzene and benzaldehyde as materials,at atmospheric pressure in DMF at 95℃ stirring for 12hours,then stirred and placed in air,after a while,filtered it,purified,then obtained the Schiff base.This reaction has a synthetic value for highly selective and mild conditions.It was a one-pot reaction and the reaction was simple and was a novel method for the synthesis of Schiff base.
Key words:Schiff base;Selenium catalyst;Nitrobenzene;Benzaldehyde
