摘要：The carbonylative Sonogashira coupling of aryl iodides with terminal alkynes was studied by using thermoregulated ligand-palladium as an efficient and reusable catalyst at 80 degrees C in water. The corresponding alkynone products were obtained in good to excellent yields under 1atm of carbon monoxide. The isolation of the products was readily achieved by extraction with ethyl acetate, and the catalyst recovered in water can be reused and recycled up to four times without significant loss in catalytic activity.
