    ZPD is a type of metal–organic framework based on zinc ions. Its structure contains 2,5 pyridine dicarboxylic acid as ligand, and it was synthesized by the hydrothermal method. Its metal–organic framework has a high surface area, suitable micropores, and a very regular crystalline structure. In this study, Biginelli reaction and chromene synthesis were realized using Cu@ZPD as a catalyst. The prepared
    ZPD是一种基于离子的属有机骨架。其结构以2,5吡啶甲酸配体,采用热法合成。其属有机骨架具有高表面积、合适的微孔和非常规则的晶体结构。本研究以Cu@ZPD为催化剂实现了Biginelli反应和色烯合成。所制备的产品具有高至优异的产率(80-96%)。通过傅里叶变换红外(FT-IR)、Brunauer-Emmett-Teller(BET)、热重分析(TGA)、X射线衍射(XRD)、场发射扫描电子显微镜(FE-SEM)对上述催化剂进行了鉴定。能量色散 X 射线 (EDX) 测绘、透射电子显微镜 (TEM) 和电感耦合等离子体发射光谱 (ICP-OES) 分析。通过使用 ICP-OES,检测到 Cu 负载量接近 3 wt%。制备的催化剂可重复使用6次而不会明显丧失催化活性。此外,还使用​​1 HNMR、13 CNMR 和 FT-IR 光谱来鉴定产物。

    A simple and efficient procedure for the one pot Biginelli Condensation Reaction of aldehydes, (beta-ketoester and urea employing SnCl4 center dot 5H(2)O /mono/di/tri-butyl-tin chloride as a novel catalyst is described. Compared to classical Biginelli reaction conditions, the present method has the advantages of good yields, short reaction times and experimental simplicity. Further, comparative efficiency of alkyl- tin chlorides in multicomponent Biginelli Condensation Reaction is also studied under solvent free conditions.
