Abstract New water‐soluble macromolecular palladium complexes with phase transfer ability were used for two‐phase Wacker oxidation of higher alkenes. Macromolecular metal complexes have been prepared employing as ligands monobutyl ether of polyethylene oxide and copolymers of ethylene oxide and propylene oxide functionalized by β,β'‐iminodipropionitrile and acetodinitrile. Macromolecular metal complexes exhibited high activity and selectivity as catalysts for Wacker oxidation of different alkenes: octene‐1, dodecene‐1, hexadecene‐1, styrene, propenylbenzene, cyclooctadiene‐1,5. The complexes based on β,β'‐iminodipropionitrile ligands showed the highest activity. All catalysts can be easily separated from product and used repeatedly without decrease of activity.
