The C (aryl) -O bond formation was generally carried out by using transition metal-catalyzed coupling reaction between aryl halide and alcohol. Among them, Cu-mediated Ullmann reaction is a powerful method for the preparation of alkyl aryl ether from secondary alcohol. In this article, recent advances in Ullmann reaction are reviewed being categorized into two parts: ligand and aryl donor.
