  Disclosed is a process for the preparation of fluorine-containing olefins comprising contacting a chlorofluoroalkene with hydrogen in the presence of a catalyst at a temperature sufficient to cause replacement of the chlorine substituents of the chlorofluoroalkene with hydrogen to produce a fluorine-containing olefin, wherein said catalyst is a composition comprising chromium, nickel and optionally an alkali metal selected from potassium and cesium. Also disclosed are catalyst compositions for the hydrodechlorination of chlorofluoroalkenes comprising copper, nickel, and an alkali metal selected from potassium and cesium, and methods of making such catalysts.

  High-fluorine-content aluminum chlorofluoride, as prepared by Cl/F exchange of aluminum chloride with one of a number of organofluorine compounds, is a very active Lewis acid capable of condensing an allylic fluoride with another fluoroolefin at low temperature. In addition to a description of broader scope, details of the selective reaction of hexafluoropropene with tetrafluoroethylene to form F-pentene-2

  通过将氯化铝与多种有机氟化合物之一进行Cl / F交换制得的高氟含量的氯氟化铝是一种非常活泼的路易斯酸，它能够在低温下使烯丙基氟与另一种氟烯烃缩合。除了更广泛的描述外，还介绍了六氟丙烯与四氟乙烯选择性反应生成F-戊烯-2的细节，以及支持多氟烯丙基阳离子物种作为中间体的证据。从头算算结果证实了所提出机制的可行性，并进一步表明，在适度的温度下，在能量上很容易获得氟代碳酸酯类化合物中的1,3-氟转移。修订的C 3 F 8（ΔH ˚F 0 = -1750±12.4千焦耳摩尔-1）和HFP（ΔH ˚F 0 = -1128±千焦耳摩尔-1）已经被算出。据报道，一些简单的金属卤化物具有氟化物亲和力。
