5′-dialdehyde by a one-pot method and fully characterized. Divalent palladium salts were coordinated to this polymer network which successfully catalyzed the nucleophilic addition reaction of arylboronic acids to aromatic aldehydes. With only 1.0 mol% heterogeneous catalyst loading, high reaction yields (> 85%) can be achieved in most cases. The scope of substrates was also investigated and the catalyst showed
以三聚氰胺和2,2'-联吡啶-5,5'-二醛为原料,采用一锅法合成了新型三聚氰胺基多孔有机聚合物(SZU-1),并对其进行了充分表征。二价钯盐与该聚合物网络配位,成功催化芳基硼酸与芳香醛的亲核加成反应。在大多数情况下,只需 1.0 mol% 的多相催化剂负载,即可实现高反应产率 (> 85%)。还研究了底物的范围,催化剂显示出普遍适用性。松散多孔的三聚氰胺基多孔有机聚合物(SZU-1)由三聚氰胺和2,2'-联吡啶-5,5'-二醛合成。SZU-1 的性能得到表征,大多数底物在催化性能测试中达到了高产率(> 85%)。
