A series of diphosphine ligand constructed porous polymers with stable and flexible frameworks have been successfully synthesized under the solvothermal conditions from polymerizing the corresponding vinyl-functionalized diphosphine monomers. These insoluble porous polymers can be swollen by a wide range of organic solvents, showing similar behavior to those of soluble analogues. Rather than just as immobilizing homogeneous catalysts, these porous polymers supported with Rh species demonstrate even better catalytic performance in the hydroformylations than the analogue homogeneous catalysts. The sample extraordinary performance could be attributed to the combination of high ligand concentration and flexible framework of the porous polymers. Meanwhile, they can be easily separated and recycled from the reaction systems without losing any activity and selectivity. This excellent catalytic performance and easy recycling heterogeneous catalyst property make them be very attractive. These diphosphine ligand constructed porous polymers may provide new platforms for the hydroformylation of olefins in the future.
一系列具有稳定和灵活骨架的双膦配体构建的多孔聚合物已经成功地在溶剂热条件下通过聚合相应的乙烯基官能化双膦单体合成。这些不溶性多孔聚合物可以被广泛的有机溶剂溶胀,表现出与可溶性类似物相似的行为。这些多孔聚合物负载 Rh 物种不仅可以作为均相催化剂的固定化,而且在氢甲酰化反应中表现出比类似的均相催化剂更好的催化性能。该样品的优异性能可归因于多孔聚合物的高配体浓度和灵活的骨架的结合。同时,它们可以很容易地从反应体系中分离和回收,而不会失去任何活性和选择性。这种优异的催化性能和易于回收的多相催化剂性质使它们非常有吸引力。这些双膦配体构建的多孔聚合物可能为烯烃的氢甲酰化反应提供新的平台。
