title: Facile synthesis of 2-alkynyl buta-1,3-dienes via Sonogashira cross-coupling methodology.
abstract: 2-alkynyl buta-1,3-dienes 4 can be synthesized in moderate to high yields by the reactions of the corresponding diiodides 1 derived from methylenecyclopropanes with substituted alkynes 2 via Sonogashira cross-coupling in the catalysis of Pd(PPh3)4/CuI.
