Recent Literature

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.
