摘要：

The new P-donor ligands PPh3-n(OC9H19)(n) (n = 3, 2, 1) containing branched alkyl chains were synthesised and their coordination to Rh-I and Pd-II studied. The X-ray structure of [Rh{PPh2(OC9H19)}(4)]PF6 was determined. Reaction of the [Rh(acac)(CO)(2)]/PPh3-n(OC9H19)(n) systems with CO/H-2 at 5 atm and 80 degrees C in toluene led to the formation of [RhH(CO)-{PPh3-(OC9H19)(n)}(3)] as the main species. The Rh-catalysed hydroformylation of 1-octene with these ligands was investigated in supercritical carbon dioxide (scCO(2)) and toluene as solvents. Although the catalytic systems are not soluble in scCO(2), they are active. The activities are higher in toluene than in scCO(2) but the selectivities for aldehydes in the case of the phosphonite derivative are higher in the supercritical medium than in toluene.
