含氯苯基的双噁唑啉类化合物的合成及表征

Synthesis of dioxadiazoline compounds containing clorobenzene group

对苯二甲酸二甲酯与水合肼反应制得对苯二甲酰肼,对苯二甲酰肼分别与4-氯苯甲醛、2-氯苯甲醛、2,4-二氯苯甲醛反应生成相应的对苯二甲酰腙,再与乙酸酐环合成3个含氯苯基的双噁唑啉化合物,并利用IR,1H NMR,MS和元素分析对3个目标化合物(4a-4c)的结构进行了表征。

Terephthalyldihydrazine was prepared by hydrazinolysis of the dimethylterephthalate. Three dioxadiazoline derivatives were synthesized by cyclization of corresponding aromatic aldehyde terephthalyldihydrazones with acetyl anhydride. Their structures were confirmed by IR, 1H NMR, MS and elemental analysis.
