Sodium Iodide → 1,1,1,2,2-Pentafluoro-8-iodooctane

Participants

Reaction Steps

1-Methylsulfonyloxy-7,7,8,8,8-pentafluorooctane(14 g, 47.01 mmol) prepared in Step 1 was dissolved in acetone(200 ml), sodium iodide(19.62 g, 130 mmol) was added thereto, and the resulting mixture was stirred overnight under reflux-heating condition. The reaction solution was diluted with excess water(1 l), extracted twice with diethylether (100 ml), washed with 1% aqueous sodiumthiosulfate solution(100 ml) and saturated saline solution, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated under reduced pressure to give 14 g(42 mmol, Yield 89%) of the title compound.
