An efficient iodine/copper(II) oxide co‐promoted direct oxidative coupling of anilines and methyl aryl ketones has been developed for the synthesis of p‐amino‐substituted unsymmetrical benzils and their iodo‐substituted derivatives. The chemoselectivity of the reactions can be easily controlled by adjusting the amount of iodine. This method exhibits good functional group tolerance for various substituents
