Copper-catalyzed coupling reaction of terminal alkynes with aryl- and alkenyliodonium salts.
[reaction: see text]. The copper iodide-catalyzed cross-coupling of terminal alkynes with hypervalent iodonium salts was accomplished with CuI (10 mol %) and NaHCO3 (2 equiv) in DME/H2O (4:1) at room temperature for 30 min to afford arylalkynes or enynes under mild conditions.
