  • 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

    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。
