and its derivatives from an aromatic aldehyde, active methylene compounds, and 2-aminobenzimidazole at room temperature under white LED irradiation. This method capitalizes on mild and environmentally friendly reaction conditions, high selectivity, and excellent yield of products, as well as the recyclability and reusability of the catalyst. In addition, the prepared benzimidazole derivatives 6d, 6k
使用不同的分析技术成功合成并表征了尖刺镍纳米颗粒,包括傅里叶变换红外光谱(FT-IR)、场电子扫描电子显微镜(FE-SEM)、透射电子显微镜(TEM)、粉末X射线衍射、振动样品磁力测定(VSM) 和能量色散 X 射线光谱 (EDS)。这些具有大表面积和磁性的纳米颗粒被精心用于从芳香醛、活性亚甲基化合物和 2-氨基苯并咪唑合成 1,2-二氢嘧啶并[1,2-a]苯并咪唑及其衍生物。室温下白色 LED 照射。该方法反应条件温和环保,选择性高,产物收率优异,且催化剂可回收和重复使用。此外,制备的苯并咪唑衍生物6d、6k和8e对胃肠道线虫模型S. obvelata表现出积极的驱虫活性。
