loaded in a melamine–terephthaldehyde based porous organic framework (MTPOF), and its catalytical activity is successfully examined for the C–S coupling reaction of 2-mercaptobenzimidazole with aryl halides and 2-halobenzoic acids. The MTPOF is synthesized by reacting melamine with terephthaldehyde, and then the copper acetate is integrated in the framework. The MTPOF and Cu@MTPOF have been characterized
在过去的几年中,多孔有机框架因其各种应用(包括多相催化)而受到广泛关注。母体多孔有机骨架的催化活性通常通过在骨架中掺入或掺杂金属离子来提高。在这种情况下,铜被负载在基于三聚氰胺-对苯二甲醛的多孔有机骨架(MTPOF)中,并成功地检测了其对 2-巯基苯并咪唑与芳基卤化物和 2-卤代苯甲酸的 C-S 偶联反应的催化活性。MTPOF是通过三聚氰胺与对苯二甲醛反应合成的,然后将乙酸铜整合到骨架中。MTPOF 和 Cu@MTPOF 已通过 FTIR、SEM、EDS、固态 NMR、BET、TGA-DTG 和 XPS 分析进行了表征。 图形概要
