| 摘 要： | 合成了两种新的氧化偶氮双苯并冠醚,改进了氧化偶氮双苯并15-冠-5的制备方法,使其收率提高到65.3%。工作中观察到,电子转移剂的离解程度对产物收率起重要作用,井以溶剂的极性给予解释。对这类双冠醚的光和热异构化做了初步探讨。

| Abstract: | Two new azoxybisbenzocrown ethers were synthesized. Preparative method of azo-xybisbenzo-15-crown-5 has been improved with the yield up to 65.3%. It was obser-ved that the degree of dissociation of electron-transfer agent plays an important role in product yield. The results were interpreted in terms of solvent polarity.Photo- and thermo-isomerization of azoxybisbenzocrown ethers have been studied preliminarily. |
