Microwave-Assisted Synthesis of Nonsymmetrical Aryl Ethers Using Nitro­arenes

An efficient, microwave-assisted ligand-free, catalyst-free synthetic method for nonsymmetrical diaryl ethers has been developed by using nitroarenes. A variety of phenols and nitroarenes was scanned by using this method to produce nonsymmetrical aryl ethers. The newly developed method is an ecofriendly and cost-­effective approach to synthesize nonsymmetrical aryl ethers.
