| 英文摘要 | heterogeneous chiral catalysts were prepared by modifying silica-supported rhodium (rh/sio2) with chiral phosphorus ligands. the chirally modified rh/sio2 catalysts exhibited high activity, regioselectivity, and enantioselectivity for the asymmetric hydroformylation of styrene and vinyl acetate. up to 72% ee and 100% selectivity of branched aldehyde for the hydroformylation of vinyl acetate were obtained for (r)-binaprh/sio2 catalysts. it is noteworthy that the modification of rh/sio2 with (s,s)-diop resulted in increased activity for the hydroformylation of vinyl acetate and gave a tof of 128 h(-1), even higher than that of the unmodified rh/sio2 catalyst (90 h(-1)). it is found that chiral modifiers with bidentate phosphines and an optimized modifier/rhodium molar ratio close to 1.0 were prerequisites for chiral induction on the chirally modified catalysts. p-31 mas nmr results and ir spectra of adsorbed co indicated that the chiral modification via the coordination of phosphines to rhodium produces chirally active sites on the rh/sio2 catalysts.
