Burmester, C.; Haß, O.; Faust, R.Science of Synthesis, (200843236.

The cross-coupling of terminal alkynes with vinyl halides forming enynes (e.g., 18) is accomplished by the use of catalytic amounts of copper(I) in the presence of phosphorus- or nitrogen-containing ligands and a suitable base (Table 2). The choice of reagents and solvent can greatly affect the outcome of the reaction.
