Dual-immobilized copper catalyst: Carbon nitride-supported copper nanoparticles catalyzed oxidation of propargylic alcohols

Article abstract of DOI:10.1016/j.tetlet.2015.01.177

Copper nanoparticles were supported and modified by carbon nitride, which was utilized as support and might work as a kind of immobilized N-donor ligand. The modified nanoparticle catalyst was evaluated with the oxidation of propargylic alcohols and showed highly catalytic efficiency as well as significant ligand or support effect in the reaction. The dual-immobilized nanoparticle catalyst could be recycled for 3 times at least without an obvious decrease in catalytic activities.
