General description
Copper turnings are a form of copper metal that has been specifically cut to have a high surface area. This form of copper is particularly useful because it provides a greater contact area for reagents to interact with which can help speed up reactions and increase yields.
Application
Copper turnings are used to synthesize inorganic salts and organometallic complexes[1] and catalysts that can be employed in a variety of synthetic transformations.[2] It is useful in:
- Synthesis of polynitro[60]fullerene.[3]
- Copper-catalyzed azide-alkyne Huisgen cycloaddition (click reaction) to synthesize 5-membered heterocycles.[4][5]
- Trifluoromethylation of heteroaromatic compounds.[6]
- Preparation of electrolyte for all-copper hybrid flow batteries.[7]
