Treatment of terminal alkynes with (diacetoxyiodo)benzene, potassium iodide, and
copper(I) iodide afforded 1-iodoalkynes in good to excellent yields under mild
conditions.

Using triethylamine as catalyst in Hunsdiecker reactions with N-halosuccinimides
as Br+ or I+ source, cinnamic acids, and propiolic acids are
converted to the corresponding α-halostyrenes and 1-halo-1-alkynes in good isolated yields within 1-5 min.
