Abstract
A series of novel phosphite ligands tri-(methoxyl polyethylene glycol)-phosphite (TMPGP) ( 1a–1d) have been synthesized and used in the rhodium-catalyzed hydroformylation of p-isobutylstyrene (IBS) in thermoregulated polyethylene glycol (PEG) biphase system. Under the conditions of P = 5.0 MPa (H 2:CO = 1:1), P/Rh = 13 (molar ratio), reaction time = 2 h and temperature = 120 °C, the conversion of IBS was 100% and the yield of aldehyde was 96%. The catalyst could be easily separated from the product by phase separation and reused for nine times without evident loss of activity.
