合成了一种多孔有机聚合物（POL-dppe），并将其用作炔选择性氢酰化反应的非均相配体。该聚合物对各种炔和β-S取代醛具有高的线性选择性和催化效率。由于微孔结构的限制效应，POL-dppe在控制缺电子炔选择性方面远优于单体dppe配体上级。首次报道了多孔有机聚合物作为区域选择性的高效配体在氢酰化反应中的应用。
A porous organic polymer (POL-dppe) was synthesized and employed as a heterogeneous ligand for selective hydroacylation of alkynes. The polymer shows high linear selectivity and catalytic efficiency toward a broad range of alkynes and β-S substituted aldehydes. Owing to the confinement effect of the microporous structure, POL-dppe was far superior to the monomeric dppe ligand in controlling the selectivity of electron-deficient alkynes. The use of a porous organic polymer as a regioselective and efficient ligand in hydroacylation is reported for the first time.
