In summary, we have developed an efficient copper-catalyzed halogenation reaction between arylboronic acids and halogen salts under oxygen atmosphere, affording ArX (X = I, Br) in moderate to good yields. The reaction showed remarkably broad substrate scope and good functional group tolerance. WebIodination of benzene is carried in the presence of oxidising agent like HIO3.
