合成了一种多孔有机聚合物（POL-xantphos），并将其用作镍催化的1，3-二炔硅氢加成反应的非均相配体。广泛的不对称和对称的1，3-二炔可以与伯硅烷和仲硅烷反应以产生相应的甲硅烷基官能化的1，3-烯炔。由于微孔结构的限制效应，POL-xantphos的选择性比单体xantphos的选择性大大提高。这是第一个报告使用的多孔有机聚合物作为一个区域选择性和有效的非均相配体在1，3-二炔硅氢加成。地球上丰富的贱金属催化剂，配合可回收的多相多孔有机聚合物，显示出良好的工业应用前景。
A porous organic polymer (POL-xantphos) was synthesized and employed as a heterogeneous ligand for nickel catalyzed highly regio- and stereo-selective 1,3-diyne hydrosilylation. A broad range of unsymmetrical and symmetrical 1,3-diynes can react with primary and secondary silanes to yield the corresponding silyl-functionalized 1,3-enynes. Owing to the confinement effect of the microporous structure, the selectivity of POL-xantphos greatly increased compared with that of the monomeric xantphos ligand. This is the first report on the use of a porous organic polymer as a regioselective and efficient heterogeneous ligand in 1,3-diyne hydrosilylation. The Earth-abundant base-metal catalyst, coordinated with a recyclable heterogeneous porous organic polymer, shows good prospects for industrial applications.
