通过用磁铁矿对谷胱甘肽(Glu)进行超声处理并在其上进一步表面固定化银,合成了异质结构的Ag纳米颗粒装饰的Fe 3 O 4谷胱甘肽(Fe 3 O 4 -Glu-Ag)纳米颗粒(NPs)。随后的磁性纳米催化剂通过傅里叶变换红外光谱(FTIR),扫描电子显微镜(SEM),高分辨率透射电子显微镜(HRTEM),粉末X射线衍射(PXRD),热重分析(TGA)进行了很好的表征。制备的Fe 3 O 4‐Glu-Ag纳米粒子已被证明是一种有效且可回收的纳米催化剂,具有低催化剂负载量,可在NaBH 4存在下使用水作为绿色溶剂将硝基芳烃和杂硝基芳烃还原为相应的胺,这种溶剂很容易在末端分离。使用外部磁体进行反应,最多可循环运行5次,而催化活性没有任何显着损失。减少4-NP的革兰氏规模研究也已成功进行,已观察到该方法可作为在工业水平上减少硝基芳烃的有效方法。

A three-step sequence has been developed for converting o-nitrobenzaldehydes into 2-nitroindoles. The key step involves the thermolysis of 2-(o-azidophenyl)nitroethylene (10) in xylenes which gives 2-nitroindole (4) in 54% yield, akin to the classic Sundberg indole synthesis. This procedure has also been utilized to synthesize 5,6-dimethoxy-2-nitroindole (14).
