A polystyrene-supported palladium(II) 1-phenyl-1,2-propanedione-2-oxime thiosemi-carbazone (PPDOT) complex is found to be a highly active catalyst for the Sonogashira coupling reactions of aryl halides with terminal alkynes. The reactions can be performed under copper- and solvent-free conditions in an air atmosphere. The palladium catalyst is easily separated, and can be reused for several times without a significant loss in its catalytic activity.
