60 °C

60 mL of acetic acid, 0.46 g sodium nitrite, TEMPO (0.35 g), CH3CO2Na (6.88 g) and 6.5 g of 2,2,3,3,4,4,5,5-octafluoro-pentan-1-ol were placed in a 100 mL1 glass flask equipped with a balloon containing oxygen, a reflux condenser and a stirrer. The mixture was stirred for 16 hr at 60° C. upon which the mixture was acidified as described in example 17 and extracted with diethyl ether (three times). The combined organic phases were washed with water and dried over magnesium sulfate. The solvent was removed at a rotary evaporator and the residue was distilled to give 3.82 g of acid (20 mmHg, 65° C.). Yield: 55%.
