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. |
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. |
