A phenanthroline-based porous organic polymer-supported heterogeneous Pd catalyst (Pd@Phen-POP) is facilely synthesized by the solvent knitting of a Phen scaffold via the Lewis-acid-catalyzed Friedel-Crafts reaction using dichloromethane as a source for linker in the presence of AlCl. The catalyst very effectively catalyzes the alkoxycarbonylation of various substituted aryl iodides with various alcohols to give corresponding products in good to excellent yields. Owing to the heterotic nature of the catalyst, it can be easily separated by simple filtration from the reaction mixture and recycled.
一种基于菲咯啉的多孔有机聚合物负载的多相钯催化剂（Pd@Phen-POP）通过以下方法简便合成：以二氯甲烷为连接体来源，在三氯化铝存在下，通过路易斯酸催化的傅克反应，对菲咯啉支架进行溶剂编织。该催化剂能非常有效地催化各种取代芳基碘化物与各种醇的烷氧羰基化反应，以良好至优异的产率得到相应产物。由于该催化剂的杂化性质，它可以通过简单过滤轻松地从反应混合物中分离出来并循环使用。
