A method for producing 1,4-bis(bromodifluoromethyl)tetrafluorobenzene (BFTFB) is disclosed. The target compound is predicted as a very potent monomer for low dielectric constant material. This method comprises the following steps: (a) mixing 1,4-bis(bromodifluoromethyl)tetrafluorobenzene (DFMTFB), a bromination agent, and a solvent (with or without) to form a mixture; (b) heating the mixture under UV radiation; and (c) purifying the resultant to obtain 1,4-bis(bromodifluoromethyl)tetrafluorobenzene (BFTFB) with high purity.
