Fluorinated vinyl iodides, R1CFCFl [where R1F, CF3, Ph, (iPrO)2P(O)], couple directly with 1-alkynes in the presence of palladium and cuprous iodide in triethylamine to give excellent yields of the fluorinated enynes.

cuprous iodide, the palladium-catalyzed coupling reaction of fluorinatedvinyl iodides with terminal alkyl and phenyl substituted alkynes gives the corresponding enynes in good yields under mild conditions. The reaction works well with perfluorovinyl, phenyl and phosphoryl substituted iodides, and the stereochemistry in the vinyl iodide was preserved in the enyne products. With a terminal dialkyne the dienyne
