coupled plasma‐optical emission spectrometry. The catalytic activity of the synthesized nanocatalyst was evaluated in green synthesis of isochromeno[4,3‐c]pyrazole‐5(1H)‐one derivatives from the reaction of ninhydrin and arylhydrazones under solvent‐free conditions. The catalyst was magnetically separated from the reaction mixture using an external magnet and recovered for five cycles without an appreciable
在本研究中,使用傅立叶变换红外,热重分析,能量分散X等多种技术,合成并表征了一种新型的可磁化催化体系,该体系涉及磁性碳纳米管(Fe 3 O 4 ‐CNT-In)上的铟纳米颗粒。射线分析,振动样品磁力法1,X射线衍射,场发射扫描电子显微镜和电感耦合等离子体发射光谱法。合成的纳米催化剂的催化活性在异色[4,3-c]吡唑-5(1 H)-茚三酮与芳基hydr在无溶剂条件下反应的一种衍生物。使用外部磁体将催化剂从反应混合物中磁性分离,并回收五个循环而其催化效率没有明显降低。在环保和负担得起的条件下进行反应,该催化剂的优点是催化剂百分率低,产物收率高,反应时间短,底物范围大且易于后处理。此外,合成的异色酚[4,3 - c ]吡唑-5(1 H)-one的四个衍生物也是新的。
