硝酸铁催化氧化二芳基乙醇酮制备二芳基乙二酮

摘要

用AcOH作溶剂,PEG400做相转移催化剂,硝酸铁能将二芳基乙醇酮催化氧化为二芳基乙二酮.产物结构用IR,MS和1H NMR光谱对其进行了表征.该方法有反应时间短,产率较高,操作简便等优点,是一种有效的由二芳基乙醇酮氧化制备二芳基乙二酮的方法.%Catalytic oxidation of 2-hydroxyl-l ,2-diaryI-ethanone to 1,2-diaryI-l ,2-ethanedione by feme nitrate using AcOH as solvent and PEG400 as phase transfer catalyst was studied. The structure of the 1,2-diaryl-l ,2-ethanedione was established by IR, MS and 1H NMR spectroscoroy. The method had advantages of short reaction time,high yield,simple work-up,low toxicity.
