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.
