A novel iminopalladacycle complex was successfully immobilized onto a metal–organic framework (MOF) through post-synthetic modification of IRMOF-3. Initially, the IRMOF-3 was modified with benzaldehyde to achieve a Schiff-base moiety in the pores of IRMOF-3 (IRMOF-3-BI) which could anchor the palladium by the addition of palladium acetate (IRMOF-3-BI-Pd). The catalyst was fully characterized by using a variety of methods such as attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), energy dispersive X-ray (EDX), inductively coupled plasma atomic emission spectroscopy (ICP-AES), X-ray photoelectron spectroscopy (XPS) and thermogravimetric analysis (TGA). Also, the structural unities of MOFs have been confirmed by scanning electron microscopy (SEM), powder X-ray diffraction (XRD) and Brunauer-Emmett-Teller (BET) analysis. Moreover, the prepared catalyst has shown excellent turnover frequencies as a heterogonous catalyst in the Suzuki C-C coupling reaction for aryl iodides, bromides and chlorides in H₂O/EtOH media at room temperature. Additionally, the catalyst can be easily isolated from the reaction mixture and recycled for five sequential runs without incredible decrease in catalytic efficiency.

通过IRMOF-3的后合成修饰，一种新型的亚氨基四环复合物成功地固定在金属-有机骨架（MOF）上。最初，IRMOF-3用苯甲醛改性，从而在IRMOF-3（IRMOF-3-BI）的孔中形成席夫碱部分，该孔可以通过添加乙酸钯（IRMOF-3-BI-Pd）来锚定钯）。使用多种方法对催化剂进行了充分表征，例如衰减全反射傅里叶变换红外光谱（ATR-FTIR），能量色散X射线（EDX），电感耦合等离子体原子发射光谱（ICP-AES），X射线光电子能谱（XPS）和热重分析（TGA）。此外，MOF的结构单位已经通过扫描电子显微镜（SEM），粉末X射线衍射（XRD）和Brunauer-Emmett-Teller（BET）分析得到确认。₂ O / EtOH介质在室温下。另外，可以容易地将催化剂从反应混合物中分离出来并循环使用五次，而催化效率却不会显着降低。
