To provide a method for producing a fluoroalkylbenzene derivative useful as a functional chemical intermediate for a medicine, an electronic material, etc., having reduced contents of residual halogens and residual metals being impurities by using a simple photohalogenation process and a halogen- fluorine exchange reaction process.
In the method for producing the fluoroalkylbenzene derivative by replacing the side chain of an alkylbenzene derivative with a halogen by a photohalogenation reaction and then subjecting the halogen-substituted alkylbenzene derivative to a halogen-fluorine exchange reaction with HF, an alkylbenzene derivative having ≤500 ppm calculated as each transition metal atom of transition metals of the group 3 to group 12 in the alkylbenzene derivative is used and HF in an amount of ≥10 times the molar amount of the halogen-substituted alkylbenzene derivative is used.
