An efficient iron-catalyzedcross-coupling reaction between alkynyl bromides and Grignard-derivedorganocuprates 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
