Versuchsvorschrift

10 g of 4,4,5,5,5-pentafluoro-2-penten-1-ol (obtained according to J. Am. Chem. Soc., 107, (1985), 5186-5191: T. Kitazume and N. Ishikawa) is dissolved in 100 cm3 of methanol, and hydrogenation is carried out in the presence of 0.5 g of Raney nickel. The catalyst is filtered, followed by washing with ethanol and after distillation at ordinary pressure, the expected alcohol is collected B.p.: 133° C. nD23: 1.3305
