Supported transition metal complexes: IV. Rhodium catalysts for the liquid phase hydroformylation of hexene-1

Abstract

Rhodium complexes have been chemically linked to organic polymers via oxygen and phosphorus ligands, and to silica via nitrogen, oxygen, phosphorus and sulfur ligands. These macromolecular complexes catalyze the liquid phase hydroformylation of hexene-1 at 80–150 °C and 42 atm carbon monoxide-hydrogen (1:1) in batch and flow tests. A species of the type RhH(CO)(PR 3 ) 3 chemically linked to silica showed no loss of activity and no detectable loss of rhodium when tested for 75 hr under continuous flow conditions.
