Paragraph 00340-0036, (2021/07/01)
The invention discloses a method for preparing fluorine-containing dihydric alcohol from fluorine-containing cycloolefin. The method comprises the following steps: oxidizing fluorine-containing cycloolefin serving as a raw material by using an oxidizing agent and treating the fluorine-containing cycloolefin by using a strong alkali to generate a solid mixed salt containing corresponding fluorine-containing dicarboxylate, and then generating corresponding fluorine-containing binary acyl chloride under the action of an acylating chlorination reagent; and finally, enabling the fluorine-containing binary acyl chloride and a reducing agent to be subjected to a reduction reaction under the action of a solvent and a catalyst to obtain the corresponding fluorine-containing dihydric alcohol. The specific organic solvent and catalyst are adopted, and other conditions are matched, so that the fluorine-containing cycloolefin can be effectively promoted to generate corresponding fluorine-containing dihydric alcohol with high efficiency and high yield. The method has the advantages of easily available raw materials, simple process, convenience in operation, low cost and the like, and is suitable for large-scale production of fluorine-containing dihydric alcohol.

Nine perfluoroacyl fluorides underwent halogen exchange when treated with anhydrous lithium halides to give acyl chlorides, bromides and iodides in high yields. The temperature dependence of this reaction is described. In the reaction with perfluorodiacyl fluoride, the diacyl halides possessing different acyl halide-groups were also produced. Of the alkaline metal salts used halogen exchange was successful only with lithium salts because of the interaction between lithium and fluorine.
