Microwave‐assisted transition‐metal‐free Sonogashira‐type coupling reactions are described. The reactions are run in water as the sole solvent, without the need for copper( I ) or any transition‐metal−phosphane complex. The scope of the methodology was tested by reaction of a wide variety of aryl halides and heteroaryl halides. The reaction was also investigated under conventional heating conditions.
