We have developed a simple and direct method for the synthesis of aryl ethers by reacting alcohols/phenols (ROH) with aryl ammonium salts (ArNMe3+), which are readily prepared from anilines (ArNR2, R=H or Me). This reaction proceeds smoothly and rapidly (within a few hours) at room temperature in the presence of a commercially available base, such as (KOBu)-Bu-t or KHMDS, and has a broad substrate scope with respect to both ROH and ArNR2. It is scalable and compatible with a wide range of functional groups.
