1-ferrocenyl-2-(3-phenyl-1H-1,2,4-triazol-5-ylthio)ethanone derivatives was synthesized by the reaction of 3-substituted-1H-1,2,4-triazole-5-thiol and chloroacetyl ferrocene in the presence of sodium hydride and potassium iodide at reflux. The structures of the new compounds were determined by IR and 1H NMR spectroscopy and HRMS. The structure of compound 5c was established by X-ray crystallography. UV–vis
通过3-取代的-1 H -1,2,4的反应合成了一系列新型的1-二茂铁基-2-(3-苯基-1 H -1,2,4-三唑-5-基硫基)乙酮衍生物-三唑-5-硫醇和氯乙酰基二茂铁在氢化钠和碘化钾存在下回流。通过IR和1 H NMR光谱以及HRMS确定新化合物的结构。通过X射线晶体学确定化合物5c的结构。在乙醇和二氯甲烷中记录了紫外可见吸收和荧光光谱。结果表明,化合物5a–g显示出相似的吸收范围从300到500 nm,最大发射带约为566 nm。荧光强度和最大发射带取决于与三唑环键合的基团。
