Comparison of Catalytic Activity of Copper Nanostructures in Friedel-crafts Type Condensation Reactions

The catalytic activity of copper nanostructures in the condensation reaction of selected indoles and aldehydes was investigated. Cu(acac)2, zeolite Y-encapsulated Cu(acac)2, free and zeolite Y-encapsulated CuO nanoparticles, and Cu2O nanoparticles were prepared successfully and characterized by mean...
