  • TEDETA@BNPs as a basic and metal free nanocatalyst for Knoevenagel condensation and Hantzsch reaction
    作者:Arash Ghorbani-Choghamarani、Zahra Heidarnezhad、Bahman Tahmasbi、Gouhar Azadi
    DOI:10.1007/s13738-018-1417-9
    日期:2018.10
    In this work, Boehmite nanoparticles (BNPs) were synthesized in water using commercially available materials and further N,N,N′,N′-tetraethyldiethylentriamin (TEDETA) was supported on the surface of BNPs, and used as organo-basic catalyst in four-component Hantzsch reaction that provides access to pharmaceutically polyhydroquinoline derivatives and Knoevenagel reaction to afford α,β-unsaturated compounds. All products were obtained in excellent yields (89–98%) and good reaction times under green condition such as water and ethanol solvents. This catalyst was characterized using FT-IR, SEM, EDS, and TGA techniques. This catalyst was reused for several times without the significant loss of their catalytic efficiency. In addition, stability of catalyst after recycling was confirmed by TGA, SEM, EDS and FT-IR techniques.
    在这项工作中,采用商业可得的材料在水中合成了水铝石纳米粒子(BNPs),并进一步在BNPs表面负载了N,N,N′,N′-四乙基二乙烯三胺(TEDETA),用于四组分汉茨施反应中的有机碱催化剂,从而获得制药用的多氢喹啉衍生物,并开展克诺文那尔反应以得到α,β-不饱和化合物。所有产物均在绿色条件下如水和乙醇溶剂中以优异的产率(89-98%)和良好的反应时间获得。该催化剂采用FT-IR、SEM、EDS和TGA技术进行表征。该催化剂在多次重复使用后,其催化效率未显著降低。此外,通过TGA、SEM、EDS和FT-IR技术确认了催化剂再生后仍具有良好的稳定性。

    日期:2017.8
    (DETA-Fe3O4) was successfully prepared as a new and well dispersed magnetically separable amine catalyst. The structure of the resulting catalyst was well characterized by a series of analysis techniques such as FT-IR, SEM, EDX, VSM, TGA and XRD. The catalytic activity of DETA-Fe3O4 was evaluated with Knoevenagel condensation of active methylene compounds with aromatic aldehydes. Interestingly, the cyclocondensation
    摘要成功制备了 固定在磁性Fe 3 O 4纳米颗粒上的二亚乙基三胺(DETA-Fe 3 O 4),作为一种新型且分散良好的磁性可分离胺催化剂。通过一系列分析技术,例如FT-IR,SEM,EDX,VSM,TGA和XRD,很好地表征了所得催化剂的结构。DETA-Fe 3 O 4的催化活性通过活性亚甲基化合物与芳族醛的Knoevenagel缩合来评估。有趣的是,DETA-Fe 3 O 4有效地催化了邻氨基苯甲酰胺和醛类的环缩合反应。在水中,所需产物(2,3-二氢喹唑啉-4(1H)-酮)的产率令人钦佩。在水性介质(水)下的催化研究也使这种合成方案成为理想的并且从环境的角度着迷。胺催化剂可以在反应后被磁性回收,并且可以多次使用而不会明显降低活性。 图形概要
