1-Alkyl-F-1-alkenyl phosphates, easily prepared from alkyl F-alkyl ketones and sodium diethyl phosphite, underwent the dephosphorylation followed by cyclocondensation in the presence of a fluoride ion catalyst and triethylamine at ambient temperature to give 3,4-di-F-alkylated furan derivatives in moderate to good yields.
