A practical and efficient method is developed for efficient synthesis of quinazoline derivatives through condensation reaction of 2‐aminoaryl ketone, an aldehyde, and ammonium acetate, over magnetic Fe3O4@SiO2‐PrNH2‐Fe3+ NPs as a recyclable nanocatalyst, under solvent‐free conditions. The as‐prepared nanocatalyst was characterized using Fourier transform infrared spectroscopy (FT‐IR), X‐ray diffraction
通过磁性Fe 3 O 4 @SiO 2 -PrNH 2 -Fe 3+上2-氨基芳基酮,醛和乙酸铵的缩合反应,开发了一种有效合成喹唑啉衍生物的实用有效方法。NP在无溶剂条件下作为可回收的纳米催化剂。使用傅立叶变换红外光谱(FT-IR),X射线衍射(XRD),场发射扫描电子显微镜(FE-SEM),透射电子显微镜(TEM),热重分析(TGA)对制备的纳米催化剂进行表征和振动样品磁力计(VSM)。温和的条件,易于加工,产品的高纯度,铁催化剂的可回收性,易得性,无毒性,经济性和环境友好性是该方法的吸引力。

A triazine based covalent organic polymer (CC-TAPT-COP) was designed and synthesized via nucleophilic substitution reaction between 1,3,5-tris-(p-aminophenyl) triazine and cyanuric chloride under refluxing conditions with bottom-up approach. The structural and morphological properties of CC-TAPT-COP were well characterized by various spectroscopic cum analytical techniques. The CC-TAPT-COP appeared
