techniques, like SEM, EDAX, TGA, PXRD, XPS, FTIR, CHN, AAS and UV-Vis analysis. The designed polymer embedded [FeII(Anthra-Merf)] complex is a remarkably successful catalyst for the synthesis of primary organic carbamates and N-substituted ureas by using safe carbonylation agent urea with different derivatives of alcohols and amines, respectively. The reported catalyst is a potential candidate towards contributing
在可持续的羰基化来源的存在下,利用新开发的多相聚合物负载的铁催化剂探索了伯氨基甲酸酯和N-取代脲的有效合成。通过将Merrifield聚合物官能化,然后接枝铁金属,合成了Merrifield锚定铁(II)-蒽催化剂[Fe II(Anthra-Merf)]。催化剂[Fe II(Anthra-Merf)]通过几种技术进行了表征,如SEM,EDAX,TGA,PXRD,XPS,FTIR,CHN,AAS和UV-Vis分析。设计的嵌入式聚合物[Fe II(Anthra-Merf)]通过使用分别与醇和胺的不同衍生物形成的安全羰基化剂脲,该配合物是合成伯有机氨基甲酸酯和N-取代脲的非常成功的催化剂。报道的催化剂是在合适的反应条件下有助于获得令人满意的分离产物产率的潜在候选者。六次运行后,该催化剂具有可循环利用的特性,几乎没有浸出,催化活性下降不明显。因此,我们发现了在中等反应条件下用于伯氨基甲酸酯和N-取代尿素合成的经济且可行的催化剂[Fe
