Abstract

Magnetic Fe₃O₄@SiO₂-2-aminothiophenol-Ni nanocomposite was synthesized and demonstrates its capability as a reusable and heterogeneous catalyst in the efficient synthesis of various 2-arylbenzothiazoles derivatives through the two-component condensation of 2-aminothiophenol with various aromatic aldehydes, and its catalytic activity was compared with Fe₃O₄@SiO₂-2-aminothiophenol-Cu. This reaction offers benign, simplicity, environmental friendliness, and cost-effectiveness. The catalyst can be easily separated and recycled by employing magnetic decantation with the using an external magnet. The characterization of the catalyst was performed using Fourier Transform Infrared spectroscopy (FT IR), Field Emission Scanning Electron Microscopy (FESEM), Transmission Electron Microscopy (TEM), Energy Dispersive X-ray Spectroscopy (EDS), Thermogravimetric analysis (TGA), Vibrating Sample Magnetometry (VSM), and X-ray diffraction (XRD) techniques.

Graphical Abstract

The findings from the evaluation of Fe₃O₄@SiO₂-2-aminothiophenol-Ni and -Cu, a new magnetically recyclable nano-structured catalyst used for the effective synthesis of 2-arylbenzothiazoles, are summarized.

Fe3O4@SiO2-2-aminothiophenol-Ni和-Cu的挑战：一种新的磁性可重复使用的纳米结构催化剂，用于高效合成2-芳基苯并噻唑

合成了磁性Fe3O4@SiO2-2-aminothiophenol-Ni纳米复合材料，证明了其作为可重复使用的多相催化剂，可通过2-氨基噻吩与多种芳香族醛的双组分缩合高效合成多种2-芳基苯并噻唑衍生物，并将其催化活性与Fe3O4@SiO2-2-aminothiophenol-Cu进行了比较。这种反应具有良性、简单、环保和成本效益的特点。利用外置磁体，采用磁滗析法，可以很容易地分离和回收催化剂。采用傅里叶变换红外光谱（FT IR）、场发射扫描电子显微镜（FESEM）、透射电子显微镜（TEM）、能量色散x射线光谱（EDS）、热重分析（TGA）、振动样品磁强计（VSM）和x射线衍射（XRD）技术对催化剂进行了表征。摘要综述了一种新型磁性可回收纳米结构催化剂-Cu对Fe3O4@SiO2-2-aminothiophenol-Ni和2-芳基苯并噻唑的评价结果。

期刊介绍： Early dissemination of important findings from Asia which may lead to new concepts in catalyst design is the main aim of this journal. Rapid, invited, short reviews and perspectives from academia and industry will constitute the major part of Catalysis Surveys from Asia . Surveys of recent progress and activities in catalytic science and technology and related areas in Asia will be covered regularly as well. We would appreciate critical comments from colleagues throughout the world about articles in Catalysis Surveys from Asia . If requested and thought appropriate, the comments will be included in the journal. We will be very happy if this journal stimulates global communication between scientists and engineers in the world of catalysis.
