摘要
设计、合成了一种新型神奇的磁性纳米催化剂 Fe3O4@APIDSO3H，并利用傅立叶变换红外光谱（FT-IR）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、X 射线衍射（XRD）、能量色散 X 射线（EDX）、热重分析（TGA）和振动样品磁力计（VSM）等不同光谱技术对其进行了表征。利用 CHNS 分析法计算了磺酸在磁性纳米催化剂上的负载百分比。然后，研究了利用该催化剂通过 Pechmann 缩合法合成各种香豆素的潜力。合成并分离出了相应的产物，产率为 60%-99%。催化剂可回收重复使用四次，催化活性未受影响。
Synthesis and Characterization of Fe3O4@SiO2@APIDSO3H as a Novel and Efficient Magnetic Nanocatalyst in Pechmann Condensation
Fe3O4@APIDSO3H as a novel and magical magnetic nanocatalyst was designed, synthesized, and characterized by different spectroscopic techniques such as Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), x-ray diffraction (XRD), energy-dispersive x-ray (EDX), thermogravimetric analysis (TGA), and vibrating sample magnetometer (VSM). The loading percentage of sulfonic acid on the magnetic nano catalyst was calculated using CHNS analysis. Then, the potential use of it was investigated for the synthesis of various coumarins by Pechmann condensation. The corresponding products were synthesized and isolated in 60%–99% yields. The catalyst was recycled and reused for four times without loss in catalytic activity.
期刊介绍：
All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
