Article abstract of DOI:10.1016/S0040-4039(00)78220-7

Palladium(0) has been found to catalyse the reaction of an aromatic carbon-iodide bond with carbon monoxide, the triple bond of alkynes and the allylic carbon of an ortho alkenoic chain to form a 3,4-disubstituted coumarin ring in satisfactory yield under
