Perfluoro- and polyfluoro-alkyl thienyl acetylenes were conveniently prepared by the following reaction sequence: Thienylmethylenetriphenylphosphorane (generated from the corresponding chloride and phenyllithium without isolation) was acylated by the addition of perfluoroacyl chloride or polyfluoroacyl chloride, respectively, to give the corresponding perfluoroacyl or polyfluoroacyl phosphoranes in
