Palladium(II) p-oxoiminatophosphane complexes were Αbstract; Palladium(II) β-oxominatophosphane complexes were used as catalysts for the Sonogashira coupling reaction. In the presence of very low amounts of the complexes, various aryl iodides and bromides were efficiently coupled with phenylacetylene even at room temperature. Furthermore, the catalysts were also effective for the reactions of aryl
