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.
