Abstract

Abstract Fe3O4@SiO2-L-proline nanoparticles have been used as an effective catalyst for the preparation of pyrimidines by three-component reactions of 1,3-dimethylbarbituric acid, aromatic aldehydes and 4-methyl aniline or 4-methoxy aniline under reflux condition in ethanol. Fe3O4@SiO2-L-proline nanoparticles have been characterized by scanning electronic microscopy (SEM), powder X-ray diffraction (XRD), vibrating sample magnetometer (VSM), thermal gravimetric analysis (TGA), energy dispersive X-ray (EDS), dynamic light scattering (DLS) and FT-IR spectroscopy. This method provides several advantages including, the reusability of the catalyst, low catalyst loading, atom economy, short reaction times and high yields of products.

嘧啶的合成Fe3O4@SiO2-L-proline纳米粒子

摘要Fe3O4@SiO2-L-proline在乙醇回流条件下，1，3-二甲基巴比妥酸、芳香醛与4-甲基苯胺或4-甲氧基苯胺的三组分反应制备嘧啶时，纳米粒子已被用作有效的催化剂。Fe3O4@SiO2-L-proline通过扫描电子显微镜（SEM）、粉末X射线衍射（XRD）、振动样品磁强计（VSM）、热重分析（TGA）、能谱仪（EDS）、动态光散射（DLS）和红外光谱对纳米颗粒进行了表征。该方法提供了几个优点，包括催化剂的可重复使用性、低催化剂负载量、原子经济性、短反应时间和高产物产率。
