In this paper, a novel catalyst is introduced based on the immobilization of palladium onto magnetic Fucus Vesiculosus extract (Pd@mFuVe catalyst). For the synthesis of Pd@mFuVe catalyst, Fucus Vesiculosus extract is obtained from the plant source, followed by the synthesis of superparamagnetic iron oxide nanoparticles (SPION) onto the extract. The catalyst is characterized by several methods, including scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), FT-IR spectroscopy, vibrating sample magnetometer (VSM), powder X-ray diffraction analysis (XRD), and inductively coupled plasma (ICP). The activity of Pd@mFuVe catalyst is studied in the synthesis of N-alkyl-2-(4-methyl-1-oxoisoquinolin-2(1H)-yl)-2-phenylacetamides. The products were synthesized in three steps, the synthesis of 2-iodobenzoic acid from 2-aminobenzoic acid, which participated in a multicomponent reaction with allylamine, aldehydes, and isocyanides, followed by a cyclization reaction, catalyzed by Pd@mFuVe catalyst. The product yields are high and the catalyst showed good reusability after 5 sequential runs. The most significant, Pd@mFuVe catalyst is fabricated from a plant extract source as a green support for the catalyst.
本文介绍了一种基于将钯固定在磁性墨角藻提取物上的新型催化剂（Pd@mFuVe催化剂）。为了合成Pd@mFuVe催化剂，从植物源获得墨角藻提取物，然后在提取物上合成超顺磁性氧化铁纳米颗粒（SPION）。通过多种方法对该催化剂进行了表征，包括扫描电子显微镜（SEM）、能量色散X射线光谱（EDS）、傅里叶变换红外光谱（FT-IR）、振动样品磁强计（VSM）、粉末X射线衍射分析（XRD）和电感耦合等离子体（ICP）。研究了Pd@mFuVe催化剂在合成N-烷基-2-(4-甲基-1-氧代异喹啉-2(1H)-基)-2-苯基乙酰胺中的活性。产物通过三步合成，由2-氨基苯甲酸合成2-碘苯甲酸，其与烯丙胺、醛和异腈参与多组分反应，然后进行环化反应，由Pd@mFuVe催化剂催化。产物收率高，该催化剂在连续运行5次后显示出良好的可重复使用性。最重要的是，Pd@mFuVe催化剂是由植物提取物源制备的一种绿色催化剂载体。
