A new approach to dendritic supported NIXANTPHOS-based hydroformylation catalysts

NIXANTHPHOS as an effective ligand in regioselective hydroformylation is modified at the nitrogen function and immobilized on soluble and solid polymer supports, such as dendrimers, polyglycerol and polyurethanes. The new ligands were tested in rhodium catalyzed regioselective hydroformylation and proved to be selective and reusable. Polymer supports require spacers between the ligand and the supporting units.
