Allylic halides and terminal alkynes couple under CuI catalysis in DMSO or DMF solution. In most cases, sodium carbonate or bicarbonate is sufficient to promote the reaction; less reactive alkynes require catalytic amounts of DBU. Bifunctional alkynes and halides can be reacted selectively according to the stoichiometry used. Trimethylsilyl, hydroxyl, ester and halide groups are tolerated in the alkyne. Most halides react without allylic rearrangement. The method is suitable for the synthesis of functionalized enynes.
Reactions of Monosubstituted Acetylenic Alcohols with Allyl Halides
Veliev, M. G.,Shatirova, M. I.,Chalabiev, Ch. A.,Mamedov, I. M.,Mustafaev, A. M.

Reactions of 2-propynyl alcohol and 2-methyl-3-butyn-2-ol with mono- and dihalogenated propenes yield allylacetylenic alcohols.The kinetic study showed that the reaction rate is governed by both electronic and steric effects of substituents in the allyl halides.
