Various electron-rich aromatics could be smoothly converted into the corresponding aromatic nitriles in good yields by treatment with POCl3 and DMF, followed by molecular iodine in aqueous ammonia. The present reaction is a novel metal-free one-pot method for the preparation of aromatic nitriles from electron-rich aromatics.
