Copper (I) Chloride Catalyzed Synthesis of Diaryl Ethers in Ionic Liquids Under Mild Conditions

Abstract

The reaction of different aryl halides with aryl oxides catalyzed by CuCl in 1-butyl-3-methyl-imidazolium tetrafluoroborate [bmim][BF₄] and 1-butyl-3-methyl-imidazolium hexafluorophosphate [bmim][PF₆] ionic liquids to give diaryl ethers in 54–90% yields has been studied under mild reaction conditions.

Keywords:

• Copper(I) chloride
