Abstract
Coupling of the triphenylphosphine moiety to poly-acrylic acid and
poly-ethyleneimine respectively afford the macromolecular ligands
PAA-PNH and PEI-PNH. Reaction of the ligands with Rh(CO)2(acac)
give water-soluble complexes that are active as catalysts in the
hydroformylation ofdifferent olefins. SAP-catalysts based on
PAA-PNH are efficient in gas phase hydroformylation of propene and
in liquid phase hydroformylation of 1-octene. Hydroformylations
under biphasic conditions are very slow but addition of
sodiumdodecyl suphate (SDS) or methanol increases the rate
significantly. Catalysts using PEI-PNH as ligands show lower
stability and activity in both SAPC and biphasic applications.
