To provide a method for producing a fluorine-containing organic compound, by which the highly pure fluorine-containing organic compound having a geminal difluoro structure can efficiently be produced without needing a complicated separation operation.
This method for producing the fluorine-containing organic compound represented by general formula (3) is characterized by converting the ester sites of a mixture of a compound represented by general formula (1) (R1 is a 1 to 20C alkyl group, an alkyl group substituted with one or more aryl groups, an alkyl group substituted with one or more monovalent heterocyclic groups, a 3 to 8C cycloalkyl group, an aryl group, an aryl group substituted with one or more substituents, or a 1 to 20C fluoroalkyl group) and a compound represented by general formula (2) into the carboxy groups to obtain the mixture of the compound of formula (3) and the compound of formula (4), and then crystallizing the mixture.
