摘要：
Rapid palladium-catalyzed carbonylative cyclization reactions of 2-iodophenol with various alkynes have been carried out by the use of commercially available molybdenum hexacarbonyl as a convenient and solid carbon monoxide source. The reactions were conducted at 160 degrees C for 30 min with microwave heating in the presence of DIEA and DMAP in 1,4-dioxane, and afford the corresponding chromen-2-one derivatives in good yields.
