PROBLEM TO BE SOLVED: To provide a method for producing a fluorine-containing compound having an acid fluoride group at the terminal position easily with high yield.SOLUTION: There is provided a method for producing a fluorine-containing compound having an acid fluoride group at the terminal position by reacting one or two or more fluorine-containing compounds having a carboxylic acid group at the terminal position represented by the following formula (1) (where, Rf represents a perfluoroalkyl group or a perfluoroalkylene group; n is 1 or 2; a, b, c and d are an integer of 0 or 1; a+b+d is 1 or more) with an alkali metal or an alkali metal compound to form a carboxylate and followed by heating at 100°C or more to carry out a thermal decomposition reaction. |
