Abstract: Novel fluoroalkyl ethers, typically (CF3)2CF-O-CH2-CH2-Br, are prepared by reacting a ketone with an alkali metal fluoride, then reacting the resulting intermediate with a dihaloethane. These ethers may be dehydrohalogenated by reaction with alcoholic KOH to yield the corresponding fluoroalkyl vinyl ethers, e.g., (CF3)2CF-O-CH=CH2. The vinyl derivatives are useful for providing oil- and water-repellent coatings on fibrous materials, e.g., fabrics.

Abstract translation: 通常，通过使酮与碱金属氟化物反应，然后使所得中间体与二卤代乙烷反应制备新的氟代烷基醚（通常为（CF 3）2 CF 2 -O-CH 2 -CH 2 Br）。 这些醚可以通过与醇KOH反应脱卤化氢，得到相应的氟烷基乙烯基醚，例如（CF 3）2 CF-O-CH = CH 2。 乙烯基衍生物可用于在纤维材料（例如织物）上提供防油和防水涂料。

Abstract: HALIDES CAN BE MADE TO UNDERGO TRANSHALOGENATION IN A PROCESS WHEREIN TWO COMPOUNDS CONTAINING DIFFERENT HALOGEN SUBSTITUENTS ARE CONTACTED AT ELEVATED TEMPERATURES. BY THIS PROCESS, ORGANIC HALIDES, SUCH AS VINYL BROMIDE AND DIBROMOETHANE, CAN BE DIRECTLY CONVERTED TO VINYL CHLORIDE BY CONTACT WITH A SUITABLE HALIDE SUCH AS HYDROGEN CHLORIDE. ETHYLENE, WHICH IS EASILY BROMINATED, CAN THUS READILY BE CONVERTED TO VINYL CHLORIDE.
