实验步骤: A supply of BCTFB was obtained by reacting ethylene with dibrominated CTFE in 1,1,1,3,3-pentafluorobutane at 120° C. for 4 hours using a mixture of tert-butyl peroxypivalate (TBPPi, 3 mol %) and 2,5-bis(tert-butylperoxy)-2,5-dimethylhexane (Trigonox 101, 4.5 mol %) as radical initiators, with the resulting structure being Br—CF2—CFCl—CH2—CH2—Br after distillation under vacuum. This was dehydrochlorinated with KOH in refluxing methanol for 15 hours, forming Br—CF2—CFCl—CH═CH2 (BCTFB). Successful radical copolymerization of CTFE (96 mol % in the feed) with BCTFB initiated by TBPPi (2 mol % with respect to both monomers) was carried out at 74° C. in a 100 mL autoclave. The 19F NMR spectrum of the obtained polymer is shown in FIG. 7. A supply of BCTFB was obtained at 120° C. for 4 hours after distillation under vacuum in refluxing methanol for 15 hours

实验步骤: A mixture of 1,4-dibromo-2-chloro-1,1,2-trifluorobutane (XVI) (7.5 g, 24.6 mmol), 1-methyl-2-pyrrolidinone (14 mL) and water (2.5 mL) was heated at 130° C. for 16 hours. The mixture was cooled to room temperature, diluted with water (80 mL) and extracted with ether (2×75 mL). The ether extract was washed with water (31×40 mL), brine, and dried over anhydrous magnesium sulfate. The residue obtained after evaporation of the solvent was chromatographed over silica gel to give 2.9 g (49%) of the desired alcohol as a clear oil. The mixture was cooled to room temperature extracted with ether (2×75 mL) The ether extract was washed with water (31×40 mL), brine dried over anhydrous magnesium sulfate The residue obtained after evaporation of the solvent was chromatographed over silica gel
