MACROCOMPLEXES ON THE BASIS OF FUNCTIONALIZED POLYETHYLENE GLYCOLS AND COPOLYMERS OF ETHYLENE-OXIDE AND PROPYLENE-OXIDE - SYNTHESIS AND CATALYSIS

Water soluble catalysts combining the properties of metal complexes an d surfactants on the basis of terminally functionalized polyethylene g lycols and block-copolymers of ethylene oxide and propylene oxide with various combinations of ethylene and propylene oxide fragments were i nvestigated. Polymers, functionalized by dipyridyl and acetylacetone w ere used as ligands for preparation of Fe(III) and Co(II) complexes, w hich showed a high activity and selectivity in oxidation of cyclohexan e and ethylbenzene by both hydrogen peroxide and oxygen. An aqueous ph ase hydroformylation rhodium catalyst was prepared on the basis of pol yethylene glycols functionalized by phosphine groups.
