摘要:
Novel catalytic systems for the Rh-catalyzed hydroformylation of dicyclopentadiene have been developed using tris-H-8-binaphthyl monophosphite as ligands containing different ester substituents at the 2'-binaphthyl position (OCOMe, OCOPh, OCOAdamantyl and OCOPhCI). The catalysts exhibited high activity (S/C = 4000, TON = 3286) with good to excellent selectivity towards dialdehydes. Remarkably, the Rh(I) complex bearing the ligands with chlorophenyl ester substituents led to 99.9% conversion and 98.7% selectivity for dialdehydes under relatively mild conditions (6 MPa, 120 degrees C).
