An intramolecular Wittig reaction has been successfully applied to the synthesis of perfluoro- and polyfluoroacetylenic thiolesters in excellent yields. These thiolesters would be expected to be good dipolarophiles and dienophiles and useful species for the synthesis of fluorinated heterocyclic compounds.
