実験手順
First, 9.1 g (50 mmol) of 2,2,3,4,4,4-hexafluorobutan-1-ol was dissolved in 40 ml of water, to which 14.7 g (50 mmol) of potassium dichromate and 17 ml of concentrated sulfuric acid, and the mixture was heated at 100° C. for 3 hours. After cooling, the reaction mixture was extracted with diethyl ether. The organic layer was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure to give 9.0 g of 2,2,3,4,4,4-hexafluorobutyric acid.
