Novel palladium-doped nanoporous carbon composite material obtained via thermolysis of amorphous zeolitic imidazolate framework (aZIF) was synthesized and used as an efficient catalyst on Suzuki–Miyaura cross-coupling reactions of aryl bromides. With this developed catalytic system, the Suzuki–Miyaura cross-coupling reaction was accomplished in aqueous solutions, and biaryls were obtained in good to excellent yields in a short reaction time. The APC-750@Pd catalyst was characterized by Fourier Transform Infrared spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Eicroscopy (SEM), X-ray Photoelectron Spectroscopy (XPS), Transmission Electron Microscopy (TEM), Thermal Gravimetric Analysis (TGA), Differential Thermal Analysis (DTA), Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Brunauer–Emmett–Teller (BET) analysis tecniques. N-doped porous carbon material (NPC-1000) was synthesized by thermolysis from aZIF. Activated porous carbon material (APC-750) was fabricated via fused at 750°C with KOH from NPC-1000. The APC-750@Pd was obtained as a result of the interaction of APC-750 and PdCl2 in deionized water. The cross-coupling reaction of different aryl bromides with phenylboronic acid was investigated to show the potential of the APC-750@Pd in the Suzuki–Miyaura cross-coupling reactions. The APC-750@Pd catalyst could be recycled at least five times with a 15% loss of catalytic efficiency in this catalytic system.

负载在氮掺杂多孔碳上的钯纳米颗粒:研究 Suzuki-Miyaura 反应的结构特性和催化活性

合成了通过非晶沸石咪唑酯骨架(aZIF)热解获得的新型钯掺杂纳米多孔碳复合材料,并将其用作芳基溴化物 Suzuki-Miyaura 交叉偶联反应的有效催化剂。使用这种开发的催化体系,Suzuki-Miyaura 交叉偶联反应在水溶液中完成,并且在很短的反应时间内以良好到极好的收率获得了联芳基化合物。APC-750@Pd催化剂通过傅里叶变换红外光谱(FTIR)、X射线衍射(XRD)、扫描电子显微镜(SEM)、X射线光电子能谱(XPS)、透射电子显微镜(TEM)、热重量分析 (TGA)、差热分析 (DTA)、电感耦合等离子体质谱 (ICP-MS) 和 Brunauer-Emmett-Teller (BET) 分析技术。N 掺杂的多孔碳材料 (NPC-1000) 是通过热解 aZIF 合成的。活性多孔碳材料 (APC-750) 是通过在 750°C 下与来自 NPC-1000 的 KOH 熔融制备的。APC-750@Pd 是 APC-750 和 PdCl 相互作用的结果2在去离子水中。研究了不同芳基溴化物与苯基硼酸的交叉偶联反应,以显示 APC-750@Pd 在 Suzuki-Miyaura 交叉偶联反应中的潜力。APC-750@Pd 催化剂在该催化系统中至少可以循环使用 5 次,催化效率损失 15%。
