摘　　要：The complex [Rh（CO）（Pz）（TPPMS）]2, （TPPMS = m-sulfonatophenyl-diphenylphosphine, Pz = Pirazolate） was evaluated as a catalyst precursor in the hydroformylation of allylbenzenes （eugenol and estragol） and terpenes （limonene and myrcene） and in the hydrogenation of α,β-unsaturated aldehydes （crotonaldehyde, cinnamaldehyde and citral） in a biphasic medium toluene/ionic liquid. Under the reaction conditions studied （P = 600 psi, T= 95 ℃, S/C = 300：1）, the rhodium system showed a high activity and selectivity towards the desired aldehydes. The catalytic phase could be recycled up to five times without any evident loss of activity or selectivity.
