Versuchsvorschrift

Into a 1.3-liter stainless steel tube was charged a mixture of iodine monochloride (130 g, 0.80 mol) and fluorosulfonic acid (88 g, 0.88 mol). The tube was sealed and cooled, then hexafluoropropylene (144 g, 0.96 mol) was transferred into the tube. The reaction mixture was kept at 25° C. for 2 hr, 50° C. for 2 hr and 80° C. for 4 hr. The product was unloaded from the shaker tube and poured into ice water. The bottom organic layer was separated, washed with water and distilled to afford the title product (120 g, 40% yield) as a clear liquid, bp. 47° C./6.7 kPa. 19F NMR (188.24 MHz, CDCl3): -74.5 (m, 3F), -77.0 (m, AB-pattern, 2F), -148.2 (m, 1F), +49.7 (m, 1F).
