A process for the production of phthaloyl dichloride compounds represented by general formula (3) by reacting a compound represented by general formula (1) with a compound represented by general formula (2) in the presence of at least one compound selected from among zirconium compounds, hafnium compounds and zinc oxide. In general formulae (1), (2) and (3), X is hydrogen, halogeno, nitro, methyl, or methoxy; when multiple X’s are present, the X’s may be the same or different from each other; n is an integer of 0 to 2; R is halogeno, chlorocarbonyl, lower alkyl, or halogen-substituted lower alkyl; when multiple R’s are present, the R’s may be the same or different from each other; and m is an integer of 0 to 2. |
