A simple synthesis of unsymmetrical buta-1,3-diynes by cross-coupling of terminal alkynes with 1-bromoalkynes in the presence of copper(I) iodide and tris(o-tolyl)phosphine was developed that gives good yields under simple and mild reaction conditions. The scope and limitations of the cross-coupling reaction were investigated. alkynes - catalysis - cross-coupling - alkadiynes
