Copper-catalyzed sonogashira-type reactions under mild palladium-free conditions.
We have developed an inexpensive catalytic system using a readily available copper/ligand combination for the Sonogashira-type cross-coupling of aryl iodides and phenyl- and hexyl-acetylene which affords disubstituted alkynes in good to excellent yields.
