摘要
以便宜无毒的水为还原剂,实现了 4-氯硝基苯的还原,发展了 1种合成4,4'-二氯氧化偶氮苯的绿色方法.反应在光照和无催化剂条件下进行,避免了传统工艺中加热和污染性还原剂及催化剂的使用.研究了多种条件对反应的影响.结果表明:1,4-二氧六环是最佳溶剂;在光功率和波长分别为75 W和365 nm时,目标产物的产率最高,达到92％.
Abstract
Cheap and non-toxic water was used as the reducing agent to enable the reduction of 4-chloronitrobenzene,which provided a new and green method for the synthesis of 4,4,-dichloroazoxybenzene.Moreover,the reaction was carried out under light-free and catalyst-free conditions,avoiding the heating and the use of polluting reductants and catalysts in traditional processes.Effects of various conditions on the reaction were studied.The results show that 1,4-dioxane is the optimal solvent.When the optical power and wavelength are 75 W and 365 nm,respectively,the target product is obtained in the highest yield 92％.
