iodoethynes with arylboronicacidsunderaerobicconditions has been developed. In the presence of palladium(II) acetate and cesium carbonate, a variety of iodoethynes underwent the Suzuki-Miyaura cross-coupling reaction with arylboronicacids at room temperature to afford the corresponding internal alkynes in moderate to good yields. It is noteworthy that this protocol proceeds under mild and aerobic conditions
