A highly porous Zn‐based metal–organicframework (MOF) IRMOF‐3 was covalently decorated with pyridine‐2‐aldehyde. The free amine group of IRMOF‐3 upon condensation with pyridine‐2‐aldehyde affords a bidentate Schiff‐base moiety in the porous matrix. The Schiff base moieties are availed to anchor copper(II) ions to display the catalyst’s utility towards catalytic reactions. The catalyst was characterized
高度多孔的锌基金属-有机骨架(MOF)IRMOF-3与吡啶-2-醛共价修饰。与吡啶-2-醛缩合后,IRMOF-3的游离胺基在多孔基质中提供双齿席夫碱部分。席夫碱部分可用于锚定铜(II)离子,以显示催化剂对催化反应的效用。通过紫外/可见光和红外光谱,粉末XRD光谱,SEM能量色散X射线光谱和氮吸附测量对催化剂进行了表征。在Cs 2 CO 3存在下,在温和条件下(90°C),该催化剂在DMSO介质中催化含氮杂环与芳基溴的N-芳基化反应具有出色的催化活性。。由于MOF的孔内存在活性位点,因此多孔催化剂表现出对底物的尺寸选择性。在多达五个连续的催化循环中,锚固的配合物似乎在催化反应过程中不会被浸出或分解,这显示出优于均相催化的实际优势。

Construction of porphyrin-based photocatalyst comprising pyridinium ionic liquid moiety for the metal-free visible light-assisted <i>N</i>-arylation of amines: facile approach to afford drug intermediates
proficient photocatalyst for the arylation of various N-heterocycles with inactivated/activated aryl halides. The photocatalytic cross-coupling was achieved under metal/base/ligand-free conditions in a laboratory-made photoreactor under the exposure of 5 W white LED light and ambient conditions. Similarly, this protocol was also appropriate for a variety of N-heterocycles, offering N-substituted aryl/alkyl
