    摘要:
    在这项研究中,Fe 3 O 4 @ GO @ Zn-Ni-Fe层状双氢氧化物的纳米复合材料被合成为新型和高效的介孔磁性纳米催化剂。合成是通过将Fe 3 O 4 MNP(磁性纳米颗粒)固定在氧化石墨烯上,然后在Fe 3 O 4的成分上形成Zn-Ni-Fe层状双氢氧化物部分来进行的@去。然后使用SEM,EDX,FTIR,XRD,TEM和VSM分析对氧化石墨烯/层状双氢氧化物体系进行表征。制备的复合体系的催化活性进一步研究了芳香醛与4-羟基香豆素在水中的一锅Knoevenagel-Michael反应。所有反应均在回流条件下进行,在3-40分钟内得到双香豆素类物质,收率为87-95%。该方法在温和的反应条件,较短的反应时间,利用水作为环境友好的溶剂以及应用可磁分离的催化剂体系方面具有显着的优势。

    In an attempt to find a new class antibacterial agents, a series of biscoumarins (1–4) and dihydropyrans (5–13) were successfully prepared. The molecular structures of four representative compounds, that is, 4, 5, 8 and 12 were confirmed by single crystal X-ray diffraction study. These synthesized compounds were screened for their antibacterial activity in vitro against Staphylococcus aureus (S. aureus ATCC 29213), methicillin-resistant S. aureus (MRSA XJ 75302), vancomycin-intermediate S. aureus (Mu50 ATCC 700699), USA 300 (Los Angeles County clone, LAC), Staphylococcus epidermidis (S. epidermidis ATCC 14990), methicillin-resistant S. epidermidis (MRSE XJ 75284) and Escherichia coli (E. coli ATCC 25922). Additionally, there are two classical intramolecular O–H···O hydrogen bonds (HBs) in biscoumarins 1–4 and the corresponding HB energies were further performed with the density functional theory (DFT) [B3LYP/6-31G*] method.
    为了寻找新型抗菌剂,成功合成了一系列双香豆素(1–4)和二氢喃(5–13)。通过单晶X射线衍射研究确认了四个代表性化合物的分子结构,即4、5、8和12。这些合成的化合物在体外进行了抗菌活性筛选,针对的菌株包括黄色葡萄球菌(S. aureus ATCC 29213)、耐甲氧西林黄色葡萄球菌(MRSA XJ 75302)、万古霉素中介黄色葡萄球菌(Mu50 ATCC 700699)、美国300群体(洛杉矶县克隆,LAC)、表皮葡萄球菌(S. epidermidis ATCC 14990)、耐甲氧西林表皮葡萄球菌(MRSE XJ 75284)和大肠杆菌(E. coli ATCC 25922)。此外,双香豆素1–4中存在两个经典的分子内O–H···O氢键(HB),并进一步利用密度泛函理论(DFT)[B3LYP/6-31G*]方法计算了相应的氢键能量。

    nanocatalysts in refluxing H2O within 12‒45 min to afford biscoumarin materials in 84–96% yield. The obtained results exhibited that catalytic activity of the Ni(II)-composite system was higher than the Cu(II)-analogue. Moreover, reusability of the nanocatalysts was examined for five consecutive cycles without the significant loss of the catalytic activity.

    In this study, nanoparticles of CuFe2O4@SiO2@PTMS@Tu@Ni(II) as the reusable magnetic catalyst were prepared. Synthesis of the Ni(II)–CuFe2O4 system was carried out through a five-step procedure including the preparation of CuFe2O4 as the prime magnetic core, layering of silica, 3-chloropropyltrimethoxysilane and thiourea and finally the immobilization of Ni(OAc)2·4H2O. The prepared nanocomposite system
