Embodiment 1
[0028] Dissolve 1.40g 3-methoxy 1,4-hydroquinone, 6.68g decafluorobiphenyl, 1.04g 1,5-pentanediol in 50ml N,N-dimethylacetamide, add the catalyst cesium fluoride 4g, the mixture was heated to 60°C, and reacted at this temperature for 18h. The reactant was precipitated in a large amount of methanol, washed with water several times, and dried to obtain a white solid. The upper product was dissolved in 30 mL of dichloromethane, and the reaction temperature was kept at about 0°C during the ice bath reaction. Then slowly drip in containing BBr 3 CH 2 Cl 2 的 solution 5mL, of which BBr 3 The content is 6.06mmol. After the addition is complete, react at room temperature for 24 hours. The reactant was precipitated in methanol, washed with water several times, and dried to obtain a white solid product. The upper reaction product was dissolved in 20 mL of epichlorohydrin, the temperature was raised to 55°C, and 0.50 g of sodium hydroxide was added every half an hour for a total of ten ...
