| 中文摘要 | 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. |
