An arylation of allylic and benzylic alcohols with diaryliodonium salts yields alkyl aryl ethers under mild and metal-free conditions. Phenols are arylated to diaryl ethers in good to excellent yields. The reaction employs diaryliodonium salts and sodium hydroxide in water at low temperature, and avoids the use of excess amounts of the coupling partners.
