A highly efficient and practical protocol for the coupling of terminal alkynes with aryl iodides is catalyzed by the inexpensive and environmentally benign combination of Fe/Cu. The versatility, generality, low cost, and environmental friendliness, in combination with exceptionally high reaction rates, render this method particularly attractive for industrial applications.
