We have developed a simple and easy-handling procedure for copper-catalyzed cyanation of aryl halides using K4[Fe_6] as the cyanide source. The present procedure has ligand- and base-free advantages, and was accomplished under the conditions of exposure to the air without degassing of the solvent.4. We carried out the selective control of preparation for phenyl ether and phenol from iodobenzene with 10 mol% of Cu_2·H_2O as the catalyst under the condition of exposure to air.
