Synthesis of Diarylalkynes by Iron/Copper Co-Catalyzed Decarboxylative spsp2 Coupling of Alkynyl Carboxylic Acids and Aryl Halides

The highly effective decarboxylative sp‐sp2 coupling of alkynylcarboxylic acids with various aryl halides was carried in the presence of low‐cost and readily available copper(I) iodide/iron(III) acetylacetonate under ligand‐free and palladium‐free conditions using low catalyst loadings. This protoco...

Description
Summary:The highly effective decarboxylative sp‐sp2 coupling of alkynylcarboxylic acids with various aryl halides was carried in the presence of low‐cost and readily available copper(I) iodide/iron(III) acetylacetonate under ligand‐free and palladium‐free conditions using low catalyst loadings. This protocol makes such coupling reactions more practical and useful.
