Eco-friendly co-catalyst-free cycloaddition of CO2 and aziridines activated by a porous MOF catalyst

Cycloaddition of CO2 with aziridines is an important reaction to obtain high-value products. Porous MOFs can catalyze this reaction, but co-catalysts are still necessary to improve the catalytic performance. Such a reaction catalyzed by MOFs-based materials without co-catalyst has not been reported hitherto. Herein, a porous and stable three-dimensional (3D) framework {[Ni(DCTP)]·6.5DMF}n (1) with a large Langmuir surface area of 3,789 m2/g was synthesized, which displayed high I2 adsorption ability up to 731.0 mg/g and could release it reversibly. Additionally, it exhibited a high CO2 adsorption capacity of 104.0 cm3/g at 273 K. The investigation results revealed 1 could effectively catalyze the cycloaddition of CO2 and aziridines in the absence of additional co-catalyst, and it could maintain the catalytic activity after five cycles. Furthermore, 1 also exhibited high catalytic activity for the gram-scale experiment. Importantly, it is the first MOF material as a heterogeneous catalyst for the conversion of CO2 and aziridines without co-catalyst. [Figure not available: see fulltext.].

Two Stable Heterometal-MOFs as Highly Efficient and Recyclable Catalysts in the CO2 Coupling Reaction with Aziridines

Two stable heterometal-organic frameworks, {Na[LnCo(DATP)2(Ac)(H2O)](NO3)?DMA?11 H2O}n (Ln=Er(1) and Yb(2)), have been prepared with H2DATP (4′-(3,5-dicarboxyphenyl)-2,2′:6′,2′′′-terpyridin

Environmentally benign chemical fixation of CO2 catalyzed by the functionalized ion-exchange resins

Basic ion-exchange resins, one kind of polystyryl-supported tertiary amine, were demonstrated to be highly efficient and recyclable catalysts for the fixation of carbon dioxide with aziridines under mild conditions, leading to the formation of 5-aryl-2-oxazolidinone with excellent regio-selectivities. Notably, neither solvents nor any additives were required, and the catalyst could be recovered by simple filtration and directly reused at least five times without significant loss of catalytic activity and selectivity. The present protocol has been applied to reactions of epoxides/propargyl amines with CO 2/CS2. This solvent-free process thus represents environmentally friendly catalytic conversion of CO2 into value-added chemicals and may have potential in various continuous flow reactors in industry.
