A new porous organic polymer has been prepared via copolymerization of divinyl-functionalized phosphoramidite ligand and tris(4-vinylphenyl)phosphine. The porous polymer was loaded with Rh(acac)CO to yield a supported Rh catalyst, which demonstrated good regioselectivity ( l/ b = 6.7-52.8) and high catalytic activity (TON up to 45.3 × 10) in hydroformylation of terminal and internal olefins. Remarkably, the heterogeneous catalyst can be reused at least 10 cycles without losing activity and selectivity in hydroformylation of 1-hexene.
通过二乙烯基官能化亚磷酰胺配体与三（4-乙烯基苯基）膦的共聚反应制备了一种新型多孔有机聚合物。将该多孔聚合物负载Rh(acac)CO以得到负载型Rh催化剂，该催化剂在末端烯烃和内烯烃的氢甲酰化反应中表现出良好的区域选择性（l/b = 6.7 - 52.8）和高催化活性（TON高达45.3×10）。值得注意的是，该多相催化剂在1-己烯的氢甲酰化反应中可以重复使用至少10次而不损失活性和选择性。
