Versuchsvorschrift

Ethyl 3-oxo-4,4,4-trifluorobutyrate (25 g, 0.136 mole) was heated between 100° and 180° C. under nitrogen with benzyl alcohol (14 ml, 0.136 mole) for 3 hours, the ethanol formed being distilled from the reaction mixture. The resulting pale yellow oil was distilled under vacuum to give a colourless oil (26.1 g, 78%), b.p. 81°-82° C. at 0.20 mm Hg.
