An efficient iron‐catalyzed cross‐coupling reaction between alkynyl bromides and Grignard‐derived organocuprates has been developed. A series of alkynylarenes were successfully synthesised by starting from different 1‐bromoalkynes and Grignard reagents. The methodology was successfully used for the two‐step stereoselective synthesis of combretastatins and represents a valid alternative to the classical syntheses of alkynylarenes.
