Binding via noncovalent electrostatic interactions of multiply sulfonated phosphine ligands with a soluble polyelectrolyte represents a convenient approach for immobilization of a catalytically active rhodium complex. As a polyelectrolyte, PDADMA-BArF4 (poly(diallyldimethylammonium tetrakis(3,5-bis(trifluoromethyl)phenyl)borate)) can be utilized. The polyelectrolyte-bound catalyst is active for hexene hydroformylation, and it can be recovered and recycled by ultrafiltration.
