Methyl-2-(1-methyl-2′-amino-ethane)amino-1-cyclopentenedithiocarbo-xylate was supported on the modified Fe 3 O 4 MNPs. Afterwards, Pd(OAc) 2 was immobilized on the modified MNPs and, then, the nanoparticles were analyzed using FT-IR, XRD, EDS, ICP-OSE, SEM, TGA and VSM spectroscopy. The catalytic efficiency of the prepared heterogeneous Pd-NPs was successfully examined in “Heck cross coupling reaction”, involving the reaction of butyl acrylate with various aryl halides in water. The advantages of this strategy include, easy recovery and efficient reusability of the expensive Pd-NPs, obtaining high yields of the butyl cinnamate cross-coupled products, short reaction times, and being performed in water for a wide range of substrates. Graphical Abstract A novel HcdMeen-Pd(0) complex was synthesized on the surface of modified Fe 3 O 4 MNPs and fully characterized by FT-IR, XRD, EDS, ICP-OSE, SEM, TGA and VSM spectroscopy analysis. The obtained complex was then used for Chemo And Homoselective Heck C–C cross-coupling synthesis of butyl cinnamates with in water as green solvent.

Fe3O4@HcdMeen-Pd(0) 有机-无机杂化物：作为一种新型多相纳米催化剂，用于化学和同选择性 Heck C-C 交叉偶联合成肉桂酸丁酯

2-(1-甲基-2'-氨基-乙烷)氨基-1-环戊烯二硫代羧酸甲酯被负载在改性的Fe 3 O 4 MNPs上。然后，将 Pd(OAc) 2 固定在修饰的 MNP 上，然后使用 FT-IR、XRD、EDS、ICP-OSE、SEM、TGA 和 VSM 光谱分析纳米颗粒。在“Heck 交叉偶联反应”中成功检验了所制备的多相 Pd-NPs 的催化效率，该反应涉及丙烯酸丁酯与各种芳基卤化物在水中的反应。该策略的优点包括：昂贵的 Pd-NPs 易于回收和高效可重复使用，肉桂酸丁酯交叉偶联产物的产量高，反应时间短，并可在水中进行，适用于各种底物。图形摘要 在修饰的 Fe 3 O 4 MNPs 表面合成了一种新型 HcdMeen-Pd(0) 配合物，并通过 FT-IR、XRD、EDS、ICP-OSE、SEM、TGA 和 VSM 光谱分析对其进行了全面表征。然后将获得的复合物用于以水中为绿色溶剂的肉桂酸丁酯的化学和同选择性 Heck C-C 交叉偶联合成。
