The phoszone ligand [(Ph2P)(bis-3,5-CF3-Ph)]NN=CH(penta-fluoro-Ph) transformed in liquid CO2 at room temperature in presence of [Rh(cod)(2)]OTf into [Rh(cod)(eta(2)-P,P'-Ph2POPPh2)]OTf. Replacing the O-atom in Ph2POPPh2 by a PrN-group leads to the ligand PrN(PPh2)(2) acting similarly as a bidentate ligand in [Rh(cod)(eta(2)-P,P'-PrN(PPh2)(2))]OTf. Hydroformylation of 1-octene with in situ catalysts formed by the ligands with [Rh(cod)(2)]OTf showed hydroformylation activities at 50 % conversion of 16,000 h(-1) (PrN(PPh2)(2)/[Rh(cod)(2)]OTf) and 24,000 h(-1) (phoszone/[Rh(cod)(2)]OTf), respectively.
