开发合成羰基化反应的高效多相催化剂的方法仍然是一个挑战。在此，我们报告了我们设计和精确合成酰胺功能化多孔有机聚合物（POPs）支持纳米钯的结果，并在非膦配体条件下应用于非均相钯催化炔烃氢氨基羰基化的第一个例子。具有不同官能团的多种末端炔和胺均可顺利转化为相应的支化α，β‐不饱和酰胺，产率中等至较高，具有较高的区域选择性。酰胺功能化POPs负载型纳米钯催化剂之所以具有良好的催化性能，应归因于其在分子水平上对催化活性位点的精细调控。本研究为设计非膦配体羰基化反应的多相催化剂提供了有意义的见解。
Development of an approach for synthesis of efficient heterogeneous catalyst toward carbonylation reaction remains a challenge. Herein, we report our results of design and precise synthesis of amide‐functionalized porous organic polymers (POPs) supported nano‐Pd, and its applying in the first example of heterogeneous palladium‐catalyzed hydroaminocarbonylation of alkynes under phosphine ligand‐free conditions. A wide range of terminal alkynes and amines with various functional groups are smoothly converted into the corresponding branchedα,β‐unsaturated amides in moderate to good yields with high regioselectivity. The good catalytic performance of amides‐functionalized POPs supported nano‐Pd catalyst should be attributed to fine regulation of the catalytically active sites of the heterogeneous catalyst at the molecular level. The present study provided meaningful insights to design heterogeneous catalysts for phosphine ligand‐free carbonylation reaction.
