Immobilization of a Catalytically Active Rhodim Complex by Electrostatic Interactions of Multiply Charged Phosphine Ligands with a Soluble Polyelectrolyte and Recovery by Ultrafiltration

摘要

BInding via noncovalent electrostatic interactions of multipl sulfonated phosphine ligands with a soluble polyelectrolyte represents a convenient approach for immobilization of a catalyticaly active rhodium complex. As a polyelectrolyte, PDADMA-BAr_4~F (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
