    • An industrial process for producing a fluorinated dicarbonyl compound in a high yield, wherein a dicarbonyl compound represented by the general formula R COCHR COR (wherein R represents hydrogen, halogen, or (un)substituted alkyl or aryl; R represents hydrogen, halogen, or (un)substituted alkyl or aryl; and R represents hydrogen, or (un)substituted alkyl, aryl, alkoxy or aryloxy, provided at least two groups selected from among R , R and R may be combined together to form a part of a cyclic structure which may contain a heteroatom) is reacted with fluorine (F2) 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 COCFR COR (wherein R , R and R are each as defined above).
    • 一种以高产率生产氟化二羰基化合物的工业方法,其中由通式R 1 COCHR 2 COR 3表示的二羰基化合物(其中R 1表示氢,卤素或(un) 取代的烷基或芳基; R 2表示氢,卤素或(取代的)取代的烷基或芳基;并且R 3表示氢或(未)取代的烷基,芳基,烷氧基或芳氧基,提供至少两个选自 在R 1,R 2和R 3中的一个可以结合在一起形成可以含有杂原子的环状结构的一部分)与氟(F 2)在至少一种选自 由C1-C5卤代烃和腈化合物组成的组或在pKa值为6以下的盐或酸存在下的溶剂中,得到由通式R 1 COCFR 2表示的氟化衍生物 COR 3(其中R 1,R 2和R 3各自如上所定义)。
