Abstract

Highly effective coupling of imidazoles with (E)‐vinyl halides can be achieved by using readily available iron catalysts under ligand‐free, copper‐free and palladium‐free conditions. Coupling of (E)‐vinyl bromides led to (Z)‐products predominantly, while the reactions of (E)‐vinyl chlorides afforded (E)‐isomers as the major products.
