合成10-硝基蒽酮的一种新方法

New method of synthesis for 10-nitro-9(10H)-anthracenone

在醋酸、相转移催化剂聚乙二醇存在下,蒽与硝酸铈铵反应生成10-硝基蒽酮。聚乙二醇作为相转移催化剂,可以提高反应的选择性。最佳反应条件为:n蒽∶n硝酸铈铵为1∶1.05,反应温度50℃,反应时间1.4h。10-硝基蒽酮的产率达74.1%。

In the presence of acetic acid and polyethylene glycol, anthracene reacts with cerium ammonium nitrate to form 10-nitro- 9（ 10H）-antracenone. As a phase transfer catalyst polyethylene glycol can improve the selectivity of the reaction. The results show that when the molar ratio of anthracene to cerium ammonium nitrate is 1 ： 1.05, reaction temperature 50℃, and reaction time 1.4h,the yield of 10-nitro-9（ 10H）-antracenone was 74.1% .
