Abstract: A process for the preparation of fluorinated dicarbonyl compounds of general formula (2), comprising reacting dicarbonyl compounds of general formula (1) with fluorine gas without any solvent in the presence of one or more acids selected from among trifluoromethanesulfonic acid, methanesulfonic acid, hydrofluoric acid, sulfuric acid, trifluoroacetic acid, boron trifluoride and sulfonated polymers wherein R?1, R2 and R3¿ are each hydrogen, alkyl or the like; and R?1a, R2a and R3a¿ are each the same as defined for R?1, R2 and R3¿, or alternatively when R?1, R2 and R3¿ are each hydrogen, the hydrogen may be replaced by fluorine, while when R?1, R2 and R3¿ are each optionally substituted alkyl, one or more hydrogen atoms on the α-position carbon atom to the CO-group may be replaced by fluorine. This process can give fluorinated dicarbonyl compounds in high yields and at high selectivity.
