摘要

本研究制备并表征了新型超薄 Cd-Ag-MOF@ZnO 复合纳米带（Ut-Nr Cd-Ag-MOF@ZnO C），并将其作为 Hantzsch 缩合反应中的有机催化剂，通过各种取代的芳基醛的一锅多组分缩合反应，选择性合成不对称聚氢喹啉、5,5-二甲基-1,3-环己二酮、乙酸铵和乙酰乙酸乙酯在无溶剂的传统加热条件下进行的一锅多组分缩合反应，反应时间相对较短。在优化的反应条件下，所开发的催化剂很容易回收并重复使用至少三次，其初始催化活性没有明显下降。操作简单、环境相容性好，再加上应用了可重复使用且价格低廉的异相催化剂，效率高、反应时间相对较短且收率高，这些都是所提出的合成方法的主要特点。

Synthesis and Characterization of Novel 2D Ultrathin Nanoribbons Cd-Ag-MOF@ZnO Composite as Organo-Nanocatalyst for Preparation of Polyhydroquinoline Heterocycles

Novel ultrathin Cd-Ag-MOF@ZnO composite nanoribbons (Ut-Nr Cd-Ag-MOF@ZnO C) were prepared and characterized in this research to serve as organocatalyst in Hantzsch condensation for selective synthesis of asymmetric polyhydroquinolines through a one-pot multi-component condensation reaction of various substituted arylaldehyde, 5,5-dimethyl-1,3-cyclohexanedione, ammonium acetate and ethyl acetoacetate under solvent-free conventional heating in relatively short reaction times. The developed catalysts were easily recycled and reutilized at least three times under optimized reaction conditions with no noticeable decline in their initial catalytic activities. Operational simplicity and environmental compatibility, combined with the application of a reusable and affordable heterogeneous catalyst, significant efficiency, relatively short reaction time, and good yield are among the main characteristics of the proposed synthetic approach.
