This study investigates the potential application of an efficient, easily recoverable and reusable magnetically separable FeO/KCC-1/APTPOSS nanoparticle-supported salen/Pd(ii) catalyst for C-C and C-H cross-couplings. The FeO/KCC-1/APTPOSS/salen/Pd(ii) MNPs were thoroughly characterized by using TEM, FE-SEM, TGA, XRD, VSM, FT-IR, ICP-MS, and BET. This observation was exploited in the direct and selective chemical reaction of 2-acetyl-benzaldehyde with cyclopentadiene for the synthesis of pentafulvene. The recycled catalyst has been analyzed by ICP-MS showing only minor changes in the morphology after the reaction, thus confirming the robustness of the catalyst.
本研究考察了一种高效、易于回收和重复使用的磁性可分离FeO/KCC-1/APTPOSS纳米颗粒负载的salen/Pd(ii)催化剂在C-C和C-H交叉偶联反应中的潜在应用。通过透射电子显微镜（TEM）、场发射扫描电子显微镜（FE-SEM）、热重分析（TGA）、X射线衍射（XRD）、振动样品磁强计（VSM）、傅里叶变换红外光谱（FT-IR）、电感耦合等离子体质谱（ICP-MS）和比表面积分析（BET）对FeO/KCC-1/APTPOSS/salen/Pd(ii)磁性纳米颗粒进行了全面表征。利用这一观察结果，将2-乙酰基苯甲醛与环戊二烯进行直接选择性化学反应以合成戊搭烯。通过ICP-MS对回收的催化剂进行分析，结果表明反应后催化剂的形态仅有微小变化，从而证实了该催化剂的稳定性。
