different coumarin-3-carboxylates and 2-aminophenol derivatives. The nanocatalyst increased rate and facility of the aforementioned reaction and had influence in the green synthesis of different 3-benzoxazol-2-yl-2H-chromen-2-one derivatives. The nanocatalyst was characterized by N2 adsorption–desorption, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron
摘要 采用(3-氯丙基)修饰Al-SBA-15,合成了一种新型有机-无机杂化材料CoCl2N,N'-(1,2-亚苯基)双(2-氨基苯甲酰胺)@Al-SBA-15。三甲氧基硅烷 (CPTMS),然后将配体共价连接到 CPTMS@Al-SBA-15 上,最后加入 CoCl2 形成配合物。介孔CoCl2NN'PhBIA@Al-SBA-15是通过不同香豆素-3-羧酸酯和2-氨基苯酚衍生物反应制备3-苯并恶唑-2-基-色烯-2-酮衍生物的有效催化剂。纳米催化剂提高了上述反应的速率和便利性,并对不同3-苯并恶唑-2-基-2H-色烯-2-one衍生物的绿色合成产生了影响。纳米催化剂通过 N2 吸附-解吸、傅里叶变换红外光谱 (FT-IR)、扫描电子显微镜 (SEM)、透射电子显微镜 (TEM)、粉末 X 射线衍射 (XRD) 和能量色散光谱 (EDS)。该方法的一些优点是反应条件温和,3-苯并恶唑-2-
