Abstract

In this research, a green and simple approach for bio-synthesis of Ag NPs incorporated into chitosan–glutaraldehyde (CHI–GA) polymeric material was presented. This hydrogel polymer (CHI-GA) was served as a capping and reductant agent for in situ creation of silver nanoparticles. The fabricated CHI-GA/Ag NPs were analyzed using UV-Vis, FE-SEM, EDX, elemental mapping, TEM, ICP, and XRD techniques. The results shown the particles prepares as spherical shapes with average sizes around 20-30 nm. The catalytic activity of the created CHI-GA/Ag NPs was investigated for the synthesis of propargylamines derivatives through an A³ coupling transformation including morpholine, phenylacetylene, and aldehydes. The CHI-GA/Ag NPs catalyst was successfully recycled and showed adequate stability for reuse over 7 runs without notable decrease in its performance.

壳聚糖-戊二醛聚合物负载的银纳米颗粒作为直接合成丙胺的高效、稳定的非均相催化剂

本研究提出了一种绿色、简单的壳聚糖-戊二醛（CHI-GA）聚合材料中银纳米粒子的生物合成方法。这种水凝胶聚合物（CHI-GA）被用作盖层和还原剂，用于原位生成银纳米颗粒。采用UV-Vis、FE-SEM、EDX、元素映射、TEM、ICP和XRD等技术对制备的CHI-GA/Ag纳米粒子进行了分析。结果表明，制备的颗粒呈球形，平均尺寸约为20-30纳米。研究了所制备的CHI-GA/Ag NPs通过A3偶联转化合成丙胺衍生物的催化活性，其中包括啉、苯乙炔和醛。CHI-GA/Ag NPs催化剂被成功回收，并在7次运行中表现出足够的稳定性，其性能没有明显下降。

期刊介绍： The Journal of Organometallic Chemistry targets original papers dealing with theoretical aspects, structural chemistry, synthesis, physical and chemical properties (including reaction mechanisms), and practical applications of organometallic compounds. Organometallic compounds are defined as compounds that contain metal - carbon bonds. The term metal includes all alkali and alkaline earth metals, all transition metals and the lanthanides and actinides in the Periodic Table. Metalloids including the elements in Group 13 and the heavier members of the Groups 14 - 16 are also included. The term chemistry includes syntheses, characterizations and reaction chemistry of all such compounds. Research reports based on use of organometallic complexes in bioorganometallic chemistry, medicine, material sciences, homogeneous catalysis and energy conversion are also welcome. The scope of the journal has been enlarged to encompass important research on organometallic complexes in bioorganometallic chemistry and material sciences, and of heavier main group elements in organometallic chemistry. The journal also publishes review articles, short communications and notes.
