| 中文摘要: |
| 首先以苯氧乙酰肼和二酰氯为原料反应得到一系列新的对称双酰肼化合物，再以POCl3合环得到一系列新的对称双-1,3,4-噁二唑化合物, 并考察了该系列化合物的紫外-可见吸收光谱。间苯双-1,3,4-噁二唑化合物在250 nm附近有一个明显的最大吸收峰，对苯双-1,3,4-噁二唑化合物的最大吸收发生红移，在290 nm附近有一个明显的最大吸收峰，而脂肪族双-1,3,4-噁二唑化合物没有明显的最大吸收峰，说明没有大的共轭体系，与结构相符合。所有化合物的结构经元素分析，IR，1H NMR和MS确证。 |
| 英文摘要: |
| First of all, phenoxyacetic acid hydrazide and di-acyl chloride are used to synthesize a series of novel dihydrazides, then, a series of novel symmetric bis-1,3,4-oxadiazole were synthesized by cyclization with phosphorus oxychloride, and their UV-Vis absorption were studied. UV-Vis maximum absorption peaks are located at about 250 nm of m-benzene bis-1,3,4- oxadiazole, UV-Vis maximum absorption peaks of p-benzene bis-1,3,4- oxadiazole exhibit red shift, located at about 290 nm, and alkanoic bis-1,3,4-oxadiazole did not appear UV-Vis maximum absorption peaks, show that no conjugated systems, it’s consistent with the structure. The structures of these compounds were confirmed by elemental analysis, IR, 1H NMR and MS. |
