Procedure
Perfluoroallyl iodide (CF2CFCF2I) was prepared by transferring 8.5 g of dry potassium iodide, 20 ml of tetraglyme and 42.5 millimoles of perfluoroallyl fluorosulfate by vacuum line to a 100-ml flask. The mixture was warmed to 20° C. and stirred for 12 hours in a dark room. The mixture was then fractionated through -100° C. and -196° C. traps, with the product being collected in the -100° C. trap.
