【摘要】 以4-硝基邻二甲苯为原料,经甲基自由基溴化,环合两步反应,合成了6-硝基-2,3-二腈基萘,并通过熔点测定、元素分析和红外光谱分析等方法对各步产物进行表征。通过对反应时间、反应温度以及光照时间对产物产率的影响,提出了较佳的反应条件,使6-硝基-2,3-二腈基萘的产率达到了92.6%,反应和缓,易于进行,成本较低。更多还原

【Abstract】 6-nitro-2,3-dicyanonaphthalene was synthesized from 4-nitro-o-xylene by two steps: free radical bromination and electrocyclic reaction,and the products were characterized by melting point,elementary analysis and IR spectrum analysis.The optimal synthetic conditions were obtained by changing the reaction time and reaction temperature.Under the optimal conditions,the yield of 6-nitro-2,3-dicyanonaphthalene reached to 92.6%,the cost was decreased and the reaction was easily controlled.更多还原
