described that a copper-catalyzed (10 mol%) tandem oxidativeiodination and alkyne-azide cycloaddition could be completed in the presence of the newly-found glycine-type ligands with low-cost NaI as the iodine resource. In the novel reaction system, a wide range of terminal alkyne, organic azide and inexpensive iodide could react effectively in one pot to give structurally diverse 5-iodo-1,4-subsitutied 1,2
