(SBA-15/E-SMTU-CuII) as a novel and efficient, heterogeneous mesoporous catalyst was synthesized and characterized by different techniques, such as FT-IR, BET, small-angle XRD, FE-SEM, TEM, TGA, ICP-OES and CHNS analysis. The as-synthesized catalyst revealed a superior catalytic activity towards the one-pot synthesis of tetrahydropyridine derivatives through the pseudo five-component reactions of aromatic aldehydes
铜(II)接枝的SBA-15官能化的S-甲基异硫脲胺化表溴醇(SBA-15 / E-SMTU-Cu II)是一种新颖,高效,均相的介孔催化剂,并通过FT-IR,BET,小角XRD,FE-SEM,TEM,TGA,ICP-OES和CHNS分析等不同技术进行了表征。所合成的催化剂在室温下在乙醇中通过芳族醛,芳族胺和乙酰乙酸乙酯/甲基乙酸乙酯的假五组分反应,对四氢吡啶衍生物的一锅法合成显示出优异的催化活性。重要的是,合成的中孔催化剂可以回收并重复使用至少十次,而其催化反应性没有任何明显的损失。此外,十次连续运行后回收的催化剂的TEM图像清楚地证明了在所施加的反应条件下所提供的催化剂的有利的耐久性和稳定性。
