Hexafluoroisobutene (HFIB) (32 g, 0.2 mol), aluminum chlorofluoride AlClxFy (5 g) and hexafluoropropene (30 g, 0.2 mol) were charged into a 400 mL Hastelloy™ nickel alloy reactor and agitated at 50° C. for 12 hours. The reaction mixture was poured onto ice, the organic (lower) layer was separated, dried over P2O5 and distilled to give 21 g (34% yield) of (CF3)2CFCH2C(CF3)=CF2, b.p. 80.5-81.5 (see Table 1).
