Abstract
Practical details are presented for the laboratory preparation of 2,3,3,3-tetrafluoropropene in good yield from trifluoroacetylacetone and sulphur tetrafluoride in the presence of hydrogen fluoride. The gas-phase IR spectrum of the tetrafluoropropene (b.p., −28 °C) is reproduced and a detailed analysis of the olefin's nuclear magnetic resonance (NMR) spectra ( 1H, 13C, 19F) is provided.
