摘　　要：在乙醇溶剂中以具有不同取代基的苯甲醛分别与水合肼进行缩合反应制备联亚胺席夫碱化合物,其结构通过1H NMR、13C NMR、元素分析及单晶X-射线衍射技术进行表征。实验结果表明:相对于苯甲醛与水合肼进行缩合反应而言,吸电子基团有利于缩合反应且产率较高,而供电子基团使反应困难且产率较低,所得席夫碱化合物晶体结构均为E构型。Five Di-schiff base compounds were synthesized in a simple method from condensation reaction of three aromatic aldehydes and two aromatic ketones with hydrazine hydrate under reflux using ethyl alcohol as solvent,and their structures were characterized by 1H NMR,13C NMR,elemental analysis and single X-ray diffraction.The experiment result showed that these Schiff base structures of C=N were E configurations,and aromatic aldehyde or ketone with electron withdrawing group improving the condensation reaction activity,while the electron-donating group reducing its activity.
