A metal-free method for the synthesis of 3-chalcogenyl-chromones/quinolones from chromones/quinolones and diorganyl dichalcogenides using ammonium iodide under air was developed. This approach allowed the preparation of a wide range of 3-selenyl- and 3-sulfenyl-chromones/quinolones in good to excellent yields.
