Description

Application

Copper turnings are used to synthesize inorganic salts and organometallic complexes and catalysts that can be employed in a variety of synthetic transformations. It is useful in:

• Synthesis of polynitro[60]fullerene.
• Copper-catalyzed azide-alkyne Huisgen cycloaddition (click reaction) to synthesize 5-membered heterocycles.
• Trifluoromethylation of heteroaromatic compounds.
• Preparation of electrolyte for all-copper hybrid flow batteries.
