and UV-Vis spectroscopic techniques. Then, the prepared nanomaterial was used as a simple, cost-effective, and reusable heterogeneous catalyst for the synthesis of 2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione derivatives by a one-pot, three-component condensation reaction of phthalhydrazide, cyclic diones, and aromatic aldehydes under solvent free conditions at 100 °C in a short time. This methodology
制备了一种新型的无机-有机杂化材料Al-SBA-15-
TPI / H 6 P 2 W 18 O 62,并通过
SEM,XRD,FT-IR,TGA-DTA和UV-Vis光谱技术进行了全面表征。然后,制备的纳米材料被用作一种简单,经济高效且可重复使用的非均相催化剂,用于合成2 H-
吲唑并[ 2,1- b ]邻苯二甲-1,6,11(13 H-三酮衍
生物通过邻苯二甲酰
肼,环二酮和芳族醛在无溶剂条件下于100°C下短时间内进行一锅三组分缩合反应。就高产率和低反应时间而言,该方法已被证明是有效和环境友好的,并且通过避免昂贵的或腐蚀性的催化剂,在转化范围和操作简单性方面提供了显着的改进。
