Cu(OAc)2 Catalyzed, Microwave Assisted O-Arylation of Phenols with Haloarenes Using Guanidinium Ionic Liquids as Recyclable System Under Mild Reaction Conditions

Abstract

Microwaves assisted straightforward and eco-friendly O-arylation of phenols with different substituted haloarenes has been demonstrated using Cu catalyst in guanidinium ionic liquid (GIL). The generation of the C–O bond via metal catalyst in GIL is demonstrated using green chemistry approach. This method provides an effective way to synthesize various biaryl ethers under mild reaction conditions. The effective recyclability and reusability of GIL up to five cycles have been performed very successfully which is the additional advantages of this method.
