Versuchsvorschrift

A mixture of 3-(perfluoro-n-octyl)phenol (10.24 g), potassium carbonate (4.2 g), NMP (30 mL) and 1,4-dibromo-2-butene (12.8 g) is heated to 45° C. for 2 hr. Extraction in the normal fashion and Kugelrohr distillation of the excess dibromide (0.1 mm Hg, 80° C.) gives 1-bromo-4-[3-(perfluoro-n-octyl)phenoxy]but-2-ene.
