2-PHASE WACKER OXIDATION OF ALKENES CATALYZED BY WATER-SOLUBLE MACROMOLECULAR COMPLEXES OF PALLADIUM

New water-soluble macromolecular palladium complexes with phase transf er ability were used for two-phase Wacker oxidation of higher alkenes. Macromolecular metal complexes have been prepared employing as ligand s monobutyl ether of polyethylene oxide and copolymers of ethylene oxi de and propylene oxide functionalized by beta,beta'-iminodipropionitri le and acetodinitrile. Macromolecular metal complexes exhibited high a ctivity 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 beta,beta'-iminodipropion itrile ligands showed the highest activity. All catalysts can be easil y separated from product and used repeatedly without decrease of activ ity.
