activity of this nanoparticle catalyst were exhibited in the synthesis of two series of compounds with important biological activities, namely 3,3′‐(arylmethylene)bis(4‐hydroxycoumarin) and 1‐carbamato‐alkyl‐2‐naphthol derivatives, under mild, green and solvent‐free conditions. To the best of our knowledge, this is the first study of the synthesis and application of Fe3O4@SiO2@(CH2)3Semicarbazide‐SO3H/HCl}
氨基甲酰肼在二氧化硅包覆的磁性纳米颗粒表面上用氯磺酸官能化,Fe 3 O 4 @SiO 2 @(CH 2)3氨基脲SO 3H / HCl},是一种根据绿色化学目的制备的新型布朗斯台德磁性磁性催化剂,并通过傅立叶变换红外光谱,可见光和能量色散X射线光谱,X射线衍射,扫描电子,透射进行了全面表征电子和原子力显微镜和热重分析。这种纳米颗粒催化剂的能力和优异的活性在具有重要生物活性的两个系列化合物的合成中得到了体现,即3,3'-(芳基亚甲基)双(4-羟基香豆素)和1-氨基甲酸酯-烷基-2-萘酚衍生物在温和,绿色和无溶剂的条件下使用。据我们所知,这是Fe 3 O 4 @SiO 2 @(CH2)3 Semicarbazide-SO 3 H / HCl}为布朗斯台德酸固体磁性纳米粒子。因此,本研究可以在逻辑设计,合成和任务特定的布朗斯台德酸磁性纳米粒子催化剂的逻辑设计,合成和应用顺序方面开辟一个新颖
