  fix it into valuable chemical products, functionalized dynamic metal–organic frameworks (MOFs) have been utilized not only because of their inherent cavity for accommodating CO2 but also owing to their reversible structural transformations in response to external stimuli for regulating the reaction. Herein, we report a dynamic and functional MOF [Cd3(L)2(BDC)3]2⋅16 DMF (MOF‐1 a; DMF=N,N‐dimethylformamide)

  二氧化碳（CO 2）的捕获和转化对于降低大气中CO 2的浓度很重要。为了有效地捕获CO 2并将其进一步固定在有价值的化学产品中，功能化的动态金属有机框架（MOF）不仅由于其固有的空腔可容纳CO 2而被利用，而且还由于其响应外部刺激而可逆的结构转变而被利用。用于调节反应。此，我们报告一个动态和功能MOF [CD 3（L）2（BDC）3 ] 2 ⋅ 16 DMF（MOF-1 ; DMF = Ñ，Ñ氨基三脚架咪唑配体N 1-（4-（1  H-咪唑-1-基）苄基）-N 1-（2-氨基乙基）乙烷-1,2-二胺（L）与1,4-苯二甲酸（H 2 BDC）与镉盐。MOF-1a不仅显示出空前的高催化活性[起始周转率（TON）高达9300]和广泛的底物范围，用于炔丙基胺与CO 2的羧基环化，而且由于它的动态五重互穿结构。进一步的研究表明，MOF-1 a 与复杂的生物系统相似，它显示出取决于底物大小的选择性催化特性。

  heterogeneous catalyst systems comprised of a fibrous nanosilica‐supported nano‐Ni@Pd‐based ionic liquid (KCC‐1/IL/Ni@Pd) are described for the cyclization of propargylic amines with CO2 to provide 2‐oxazolidinones. KCC‐1 with high surface area was functionalized with IL acting as a robust anchor so that the nano‐Ni@Pd was well dispersed on the fibres of the KCC‐1 microspheres, without aggregation. Because

  In this study, The HPG@KCC-1 NP was prepared through the ringopening polymerization of glycidol on the surface of KCC-1 to form HPG@KCC-1 and then HPG@KCC-1 NPs were functionalized using chlorodiphenylphosphine and phosphine-functionalized nanoparticles (HPG@KCC-1/PPh2) as a recyclable phosphorus ligand was obtained. Also, gold (III) complex of HPG@KCC-1/PPh2 ligand (HPG@KCC-1/PPh2/Au) was prepared which used for the cyclization of propargylic amines with CO2 to provide 2-oxazolidinones. High catalytic activity and ease of recovery from the reaction mixture using filtration, and several reuse times without significant losses in performance are additional eco-friendly attributes of this catalytic system.

  This study investigates the potential application of an efficient, easily recoverable and reusable KCC-1 nanoparticle-supported Salen/Ru(II) catalyst in the synthesis of 2-oxazolidinones from CO2, and propargylic amines. The KCC-1/Salen/Ru(II) NPs were thoroughly characterized by using TEM, SEM, TGA, FT-IR, ICP-MS, and BET. This observation was exploited in the direct and selective chemical fixation of CO2, affording high degrees of CO2 capture and conversion. The recycled catalyst has been analyzed by ICP-MS showing only minor changes in the morphology after the reaction, thus confirming the robustness of the catalyst.[GRAPHICS].
