Water → C4F9Och2I

Participants

Reaction Steps

C4F9OCH2Cl (50 g, 0.175 mole, isomer ratio n/i=95:5) was combined with sodium iodide (52.5 g, 0.38 mole) in acetone (200 g) and heated to reflux overnight. Water was added and the acetone distilled from the reaction vessel using a Dean-Stark apparatus. The product was washed with water to remove residual acetone. Glc of the residue (52.6 g) revealed it to be 82.6 wt. % of the desired product C4F9OCH2I, which was further purified by distillation. The distillation fraction boiling at 110-15° C. was found to be 97.8 wt. % of the desired product with a 96/4 normal to iso ratio.
