To a slurry of 130.0 g of zinc powder in 500 mL of ethanol was added 5.0 g of acetic acid. A solution of 230.0 g of the crude 10-iodo-11-(nonafluorobutyl)-1-undecanol prepared above in 100 mL of ethanol was added dropwise with stirring over 1 hr. Then, the reaction mixture was heated at 50° C. for 4 hr. The mixture was filtered, and the filtrate was concentrated to a viscous, light yellow liquid. Bulb-to-bulb distillation of the liquid, in several portions, provided 97.3 g of 11-(nonafluorobutyl)-1-undecanol as a colorless solid, b.p. 160-200° C. at 0.05 torr (7 Pa).
