الإجراء التجريبي
Trioctyl phosphine (31 g) was partially dissolved in reagent-grade acetonitrile (250 ml) in a large round-bottomed flask and stirred vigorously. 1,1,1,2,2,3,3,4,4,5,5,6,6-Tridecafluoro-8-iodooctane (44.2 g) was added, and the mixture was heated under reflux at 110 degrees C. for 24 hours. The solvent was removed under vacuum giving (3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)-trioctylphosphonium iodide as a waxy solid (30.5 g). Potassium 1,1,2,2-tetrafluoroethanesulfonate (TFES-K, 13.9 g) was dissolved in reagent grade acetone (100 ml) in a separate round-bottomed flask, and to this was added (3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)-trioctylphosphonium iodide (60 g). The reaction mixture was heated at 60 degrees C. under reflux for approximately 16 hours. The reaction mixture was then filtered using a large frit glass funnel to remove the white KI precipitate formed, and the filtrate was placed on a rotary evaporator for 4 hours to remove the acetone. The liquid was left for 24 hours at room temperature and then filtered a second time (to remove KI) to yield the product (62 g) as shown by proton NMR.
