Abstract

Bimetallic organic frameworks (bimetallic-MOFs) are considered promising catalysts due to their tunable pores, strength, and high catalytic performance. Here, a bimetallic-MOF-based on iron (Fe) and cobalt (Co) metals was designed, synthesized and characterized. Next, the synthesized bimetallic-MOFs were post-modified with phenyl isocyanate to create urea moieties that are susceptible to hydrogen bonding (H-bond) catalytic activities. Various techniques such as SEM, XRD, BET/BJH, FT-IR, TGA/DTA, EDX and elemental-mapping were used to approve the structure of the synthesized catalyst. MIL-88B(Fe₂/Co)-UR acts as an H-bond catalyst in the multi-component reaction to form pyrazolo[3,4-b]quinolines via appropriate sections with medicinal properties. The features of using MIL-88B(Fe₂/Co)-UR as an H-bond catalyst are increased efficiency, decreased reaction time and reusability of the catalyst.

新型多孔双金属 H 键催化剂在通过乙烯基异构体协同氧化法制备生物指甲花基吡唑并[3,4-b]喹啉中的应用

双金属有机框架（bimetallic-MOFs）因其可调的孔隙、强度和高催化性能而被认为是很有前途的催化剂。本文设计、合成并表征了一种基于铁（Fe）和钴（Co）金属的双金属-MOF。然后，用异氰酸苯酯对合成的双金属-MOF 进行后修饰，以生成易产生氢键催化活性的脲分子。为确定合成催化剂的结构，使用了各种技术，如 SEM、XRD、BET/BJH、FT-IR、TGA/DTA、EDX 和元素图谱。在多组分反应中，MIL-88B(Fe2/Co)-UR 可作为 H 键催化剂，通过具有药用特性的适当部分生成吡唑并[3,4-b]喹啉类化合物。使用 MIL-88B(Fe2/Co)-UR 作为 H 键催化剂的特点是效率高、反应时间短和催化剂可重复使用。
