Pyrrolylphosphines prosper: The hydroformylation of propene catalyzed by Rh(acac)(CO)₂ (acac=acetylacetonate) with a 13-fold excess of N-pyrrolylphosphine ligands PPyr₃, PPh₂Pyr, or PPh(Pyr)₂ (Pyr=NC₄H₄) is investigated under a pressure of 15 bar (propene/H₂/CO=5:5:5) at 80 °C. The N-pyrrolylphosphine ligands facilitate an excellent regioselectivity towards n-butanal aldehyde, significantly better than PPh₃ and PCy₃ under the same conditions.
