Ligand-Free Catalytic System for the Synthesis of Diarylethers over Cu₂O/Cu-CNTs as Heterogeneous Reusable Catalyst.

Tetrahedron Lett. 2013;
54: 6494-6497

Key words

phenols - aryl halides - O-arylation - diaryl ethers

Significance

Cu₂O/Cu-Coated carbon nanotubes (Cu₂O/Cu-CNTs) catalyzed the O-arylation of phenols with aryl halides under ligand-free conditions to give the corresponding diaryl ethers in up to 97% yield (20 examples).

Comment

Cu₂O/Cu-CNTs were recovered by filtration and reused three times without significant loss of catalytic activity. Lee and co-workers have previously reported the preparation and characterization of Cu₂O/Cu-CNTs (Scr. Mater. 2008, 58, 1010).
