摘要: Heterogeneous chiral catalysts were prepared by modifying or stabilizing rhodium nanoparticles with chiral phosphorus ligands such as (R)-BINAP, (S,S)-DIOP and (R,R)-Ph-BPE. 31P MAS NMR and CO-IR spectra confirm that chiral ligands modify the rhodium nanoparticles by coordinative interaction. The chirally modified/ stabilized rhodium nanocatalysts exhibit similar or even better catalytic performance than the homogeneous counterparts for the asymmetric hydroformylation of olefins. Up to 90% ee and 98% branched regioselectivity can be obtained for rhodium catalysts modified with (R,R)-Ph-BPE. A catalytic mechanism involving surface multi-site cooperation on the chirally modified rhodium nanocatalysts is proposed.
