Abstract

In this study, an efficient and magnetically recoverable catalyst consisting of 6-methylguanamine supported on CoFe₂O₄ nanoparticles for the preparation of isoxazol-5(4H)-one derivatives has been synthesized. Different physicochemical methods such as Fourier transform infrared (FT-IR), X-ray powder diffraction (XRD), and field emission scanning electron microscopy (FE-SEM) were used to characterize the obtained catalyst. The nanocatalyst reusability was investigated by using five consecutive reaction runs. The present procedure possesses some merits such as mild reaction conditions, excellent yields, short reaction time, avoidance of using organic solvents, and easy workup.

摘要

_{在这项研究中，合成了一种由负载在 CoFe 2} O ₄纳米颗粒上的 6-甲基胍胺组成的高效且可磁回收的催化剂，用于制备异恶唑-5(4 H )-酮衍生物。采用不同的物理化学方法，如傅里叶变换红外 (FT-IR)、X 射线粉末衍射 (XRD) 和场发射扫描电子显微镜 (FE-SEM) 对所得催化剂进行表征。通过使用五个连续的反应运行来研究纳米催化剂的可重复使用性。本工艺具有反应条件温和、收率高、反应时间短、避免使用有机溶剂、易于后处理等优点。
