3种新型二胺化合物的合成及其晶体结构

Synthesis and crystal structure of three kinds of diamines

以2,6-吡啶二酰氯和(邻、间、对)硝基苯胺反应合成N,N-′(2-硝基苯基)-2,6-二甲酰亚胺吡啶、N,N-′(3-硝基苯基)-2,6-二甲酰亚胺吡啶、N,N-′(4-硝基苯基)-2,6-二甲酰亚胺吡啶等3种二硝基化合物,然后以FeCl3-NH2NH2·H2O活性炭为还原体系,将3种二硝基化合物还原成相应的二胺(Ⅰ～Ⅲ).并用元素分析,FTIR和X射线单晶衍射进行了表征.

The compounds N,N′-（2-nitrophenyl）-2,6-dimethyl pyridine imide,N,N′-（3-nitrophenyl）-2,6-dimethyl-imide pyridine,N,N′-（4-nitrophenyl）-2,6-pyridine were synthesized from reaction of 2,6-pyridine chloride and（o,m,p）-nitroaniline,the three kinde of compounds were reduced by FeCl3-NH2NH2·H2O-C reduction system,and characterized by elemental analysis,FTIR and single crystal Xray diffraction.
