Abstract
Abstract Various substituted diarylether derivatives were prepared by using heterogeneous reusable Cu 2 O-and Cu-coated carbon nanotubes (Cu 2 O/Cu-CNTs) as catalyst under ligand-free conditions, which provided good to excellent yields. The catalyst was characterized by TEM, XRD, and AAS analysis. The effects of solvent, base, and amount of catalyst for the O-arylation were investigated. The catalyst could be recovered by simple ...
