✦ Synopsis

Synergic effect of iron and copper salts as catalysts for the Sonogashira-Hagihara cross-couplings of aryl iodides with terminal alkynes is demonstrated. High yields of cross-coupled products are obtained under conditions that are smoother than those using only CuI as catalyst. Furthermore no expensive or/and toxic ligand is required.

## Abstract A copper‐catalyzed cross‐coupling reaction of alkynes with aryl iodides is described. The system tolerates a broad range of functional groups and enables the use of sterically demanding substrates with only 1.0–2.5 mol‐% of Cu~2~O and 1.0–2.5 mol‐% of xantphos as the catalyst.
