An industrial process for producing a fluorinated dicarbonyl compound in a high yield, wherein a dicarbonyl compound represented by the general formula R?1COCHR2COR3¿ (wherein R1 represents hydrogen, halogen, or (un)substituted alkyl or aryl; R2 represents hydrogen, halogen, or (un)substituted alkyl or aryl; and R3 represents hydrogen, or (un)substituted alkyl, aryl, alkoxy or aryloxy, provided at least two groups selected from among R?1, R2 and R3¿ may be combined together to form a part of a cyclic structure which may contain a heteroatom) is reacted with fluorine (F¿2?) either in at least one solvent selected from the group consisting of C1-C5 halogenated hydrocarbons and nitrile compounds or in a solvent in the presence of a salt or an acid with a pKa value of 6 or less to give a fluorinated derivative represented by the general formula R?1COCFR2COR3¿ (wherein R?1, R2 and R3¿ are each as defined above). |
