选择性氧化苊制备苊酮

Synthesis of Acenaphthenone by Selective Oxidation of Acenaphthene

在醋酸、聚乙二醇存在下 ,铬酸酐和苊在温和的条件下反应 ,苊可以完全转化为苊酮。聚乙二醇作为相转移催化剂可以提高反应的选择性。通过研究铬酸酐、醋酸、聚乙二醇的用量以及反应温度、时间对苊的氧化反应的影响 。

In the presence of acetic acid and polyethylene glycol, chromic anhydride and acenaphthene react under mild condition and acenaphthene can completely convert into acenaphthenone. As a phase transfer catalyst polyethylene glycol can improve the selectivity of the reaction. The influence of the amount of chromic anhydride, acetie acid, polyethylene glycol and reaction temperature and time upon the oxidization reaction of acenaphthene is also studied so as to find the best conditions for the reaction.
