1-Octene, 1-decene and styrene have been hydroformylated using a CO2-philic fluorous ligand associated with a rhodium catalyst. The effect of P/Rh molar ratio, partial pressure of CO/H-2 and total pressure of carbon dioxide were studied. When 1-octene was used as the substrate, high conversion and selectivity in aldehydes were observed using low rhodium concentration and low P/Rh ratios.
