Diaryl ethers form an important class of organic compounds, both in life sciences and in the polymer industry. In general, diaryl ethers can be synthesized by means of copper-catalyzed Ullmann diaryl ether coupling, palladium-catalysed Buchwald-Hartwig reaction, nucleophilic aromatic substitution, arylboronic acid diaryl ether coupling, oxidative coupling, and nucleophilic aromatic addition to metal-arene complexes. This review covers the progress in diaryl ether synthesis since 1999, with literature coverage through September 2005.
