说明

一般說明

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.

應用

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.
