1-Substituted F-1-alkenyl phosphates, easily prepared from F-alkyl ketones and sodium salt of diethyl phosphite were allowed to react with various phosphonium ylides in tetrahydrofuran or hexane at room temperature or at the reflux temperature of the solvent to lead to the corresponding polyfluorinated 1,3-diene derivatives in moderate to good yields.
