PROBLEM TO BE SOLVED: To provide a method for efficiently producing 1,5-diketones useful as raw materials for various chemical products. An aromatic compound is reacted with a glutaric acid derivative or 4-aroylbutyric acid in the presence of a solid acid catalyst to produce 1,5-diketones having the same or different aromatic substituents. As the catalyst, a solid acid catalyst such as zeolite can be used. As the zeolite, those of beta type, Y type and the like can be used, and those having a silica / alumina ratio of 2 to 1000 are preferably used. [Selection figure] None |
