| 英文摘要 | the heterogenization of homogeneous catalysts is of critical importance for both fundamental research and practical applications. the key obstacle to industrial applications of heterogenized homogeneous catalysts is the long-term stability of the immobilized molecular complexes. we unambiguously demonstrate in this report that the vinyl-functionalized pph3 polymers supported single rh sites (rh/pol-pph3) catalyst provided not only excellent catalytic activity but also ultrahigh stability for fixed-bed olefins hydroformylation, which is one of the most important industrial homogeneous catalytic processes for the synthesis of aldehydes and alcohols. haadf-stem and exafs results indicated that the rh atoms were present in single rh sites which were strongly coordinated with the exposed phosphorous atoms of the pol-pph3 support. the rh/pol-pph3 catalyst provided high activity and selectivity because it maintained the catalytic functionalities similar to the homogeneous hrh(co)(pph3)(3) complex, as demonstrated both by p-31 mas nmr and in situ ft-ir experiments. thus a reaction mechanism, similar to that over the homogeneous hrh(co)(pph3)(3) complex, was proposed for olefin hydroformylation over the novel rh/pol-pph3 catalyst.
