Versuchsvorschrift
n-Butylpentafluorobenzene [19.0 g; described by J. M. Birchall and R. N. Haszeldine J. Chem. Soc p 3719 (1961)] was added to a solution of hydrazine hydrate (50 ml; 99-100% w/w) in ethanol (100 ml) and the mixture heated at reflux for 72 hours. The reaction mixture was cooled, evaporated to dryness to give a solid which was filtered off and washed with ethanol and hexane to give 4-n-butyl-2,3,5,6-tetrafluorophenylhydrazine (20.5 g), m.p. 80°-81° C., in the form of colourless crystals.
