A convenient synthesis of 5-substituted 2-perfluoroalkyl-4H-pyran-4-ones by dehydration of 2,3-dihydro-3-hydroxy-6-perfluoroalkyl-4H-pyran-4-ones is described. The 6-substituted and parent 2-perfluoroalkyl-4H-pyran-4-ones have been more successfully prepared using the condensation of alkyl enol ethers, derived from β-dicarbonyl compounds, with ethyl perfluoroalkanoates.
