In2O3-SiO2 as recyclable heterogeneous catalyst material was synthesized by an aqueous solution based wet chemistry method, i.e. hydrothermal method and utilized for the reaction between pathalic anhydride and substituted hydrazine hydrate in DMF medium to synthesize 2,3-dihydrophthalazine-1,4-dione (DHP) derivatives. The advantages of this protocol are cost effective, ease of handling and environmental
采用基于水溶液的湿化学法,即水热法合成介孔结构In2O3-SiO2作为可回收的多相催化剂材料,并将其用于邻苯二甲酸酐与取代水合肼在DMF介质中反应合成2,3-二氢酞嗪-1,4-二酮(DHP)衍生物。该协议的优点是成本有效、易于处理且环境友好。通过使用 X 射线衍射光谱、扫描电子显微镜、能量色散光谱、傅里叶变换红外光谱、程序升温解吸和 Brunauer-Emmett-Teller 对这种催化材料进行了表征。所提出的合成方法收率高、后处理过程简单、无毒、清洁,并且有利于催化体系的简单回收和重复使用。
