    摘要: The process for producing a (fluoroalkyl)benzene derivative according to the present invention comprises a step of reducing the total content of group 3 to group 12 transition metals in an alkylbenzene derivative to 500 ppm or less in terms of metal atoms; a step of halogenating the branched alkyl group of the purified alkylbenzene derivative by a photohalogenation to obtain a (haloalkyl)benzene derivative; and a step of subjecting the (haloalkyl)benzene derivative to a halogen-fluorine exchange using HF in an amount of 10 mol or higher per one mole of the (haloalkyl)benzene derivative. The (fluoroalkyl)benzene derivative produced by the process is reduced in the content of impurities such as residual halogens and residual metals, and is useful as intermediates for functional chemical products for use in applications such as medicines and electronic materials.
