Abstract

An interesting palladium‐catalyzed procedure for the synthesis of perfluoroalkylated enynes from perfluoroalkyl iodides and alkynes was developed. The reaction proceeds through the addition of iodoperfluoroalkanes to terminal alkynes and subsequent Sonogashira coupling with the same alkynes. This transformation could be conducted under mild reaction conditions with high efficiency and selectivity. Good functional group compatibility was observed, and a variety of perfluoroalkylated enynes products were isolated in good to excellent yields.
