摘要

在这项工作中，我们报告了新的硫胺素盐酸盐功能化磁性纳米颗粒（Fe3O4@SiO2-Pr-NH-TDI-VB1）催化应用。在室温条件下，苯那基溴、硫代氨基脲和芳醛在乙醚：水（50:50,v/v）中一锅三组分反应合成肼基噻唑，考察了Fe3O4@SiO2-Pr-NH-TDI-VB1的催化电位。本方法具有反应程序简单、反应时间短、五次用外磁体回收催化剂效率高、反应条件适宜、收率高等优点。所得肼基噻唑用乙醇进行简单重结晶纯化。

Synthesis, Characterization, and Catalytic Application of Novel Magnetically Separable Fe3O4@SiO2-Pr-NH-TDI-VB1 for Rapid Synthesis of Hydrazinyl Thiazoles

In this work, we report novel thiamine hydrochloride functionalized magnetic nanoparticles (Fe₃O₄@SiO₂-Pr-NH-TDI-VB1) for catalytic applications. The catalytic potential of Fe₃O₄@SiO₂-Pr-NH-TDI-VB1 was assessed in the one-pot three-component reaction of phenacyl bromide, thiosemicarbazide, and aryl aldehyde for the synthesis of hydrazinyl thiazole in EtOH:H₂O (50:50, v/v) at room temperature. The present method exhibits the advantages of a simple reaction procedure, reduced reaction time, efficient retrieval of catalyst for the five runs using an external magnet, ambient reaction condition, and excellent yields. The resultant hydrazinyl thiazoles were purified by simple recrystallization using ethanol.

期刊介绍： All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
