Nanocopper-Catalyzed Cross-Coupling Reaction for the Synthesis of Diarylethers

摘要

Nanocopper-catalyzed cross-coupling reaction of phenol and aryl halides for the synthesis of diarylethers is reported. With the optimum conditions of using nanocopper as catalyst, 1,10-phenanthroline as a ligand, cesium carbonate as a base, in DMF at 110°C under nitrogen atmosphere, varieties of diarylethers were synthesized at moderate to good yields. This method avoids the use of palladium and/or expensive additives.
