Polymer-supported quaternary phosphonium salt (PS-QPS) was explored as effective catalyst for the coupling reaction of carbon dioxide with epoxides. The results indicated that cyclic carbonates with high yields (98.6%) and excellent selectivity (100%) could be prepared at the conditions of 5 MPa CO2, 150°C, and 6 h without the addition of organic solvents or cocatalysts. The effects of various reaction conditions on the catalytic performance were investigated in detail. The catalyst is applicable to a variety of epoxides, producing the corresponding cyclic carbonates in good yields. Furthermore, the catalyst could be recovered easily and reused for five times without loss of catalytic activity obviously. A proposed mechanism for synthesis of cyclic carbonate in the presence of PS-QPS was discussed. The catalyst was characterized by thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and Fourier transform infrared (FT-IR) spectrum. It is believed that PS-QPS is of great potential for CO2fixation applications due to its unusual advantages, such as easy preparation, high activity and selectivity, stability, low cost, and reusability.

Strong Acid Sites

Mild reaction conditions (nearly room temperature and atmospheric CO2 pressure) for the cycloaddition of CO2 with epoxides to produce cyclic carbonates were investigated applying MIL-101(Cr) as a catalyst. The MIL-101 catalyst contains strong acid sites, which promote the ring-opening of the epoxide substrate. Moreover, the high surface area, enabling the adsorption of more CO2 (substrate), combined with a large pore size of the catalyst is essential for the catalytic performance. Additionally, epoxide substrates bearing electron-withdrawing substituents or having a low boiling point demonstrated an excellent conversion towards the cyclic carbonates. MIL-101(Cr) for the cycloaddition of carbon dioxide with epoxides is demonstrated to be a robust and stable catalyst able to be re-used at least five times without loss in activity.

Based on the ligand H2dpPzda (1), a novel cobalt complex [Co(H2dpPzda)(NCS)2]·CH3OH(2) has been synthesized and characterized. The Complex 2 exhibited excellent catalytic performance for converting CO2 into cyclic carbonates under mild conditions. For propylene oxide (PO) and CO2 synthesis of propylene carbonate (PC), the catalytic system showed a remarkable TOF as high as 29,200 h−1. The catalytic system also showed broad substrate scope of epoxide. Additionally, the catalyst could be recycled to maintain the integrity of the structure and remained equal to the level of its catalytic activity even after seven catalytic rounds. Additionally, a possible catalytic mechanism was proposed due to the high catalytic activity which might be owing to the synergism of Lewis acidic metal centers and N group.

Abstract. A novel type of multifunctional nanocatalysts (La-/Sm-PMO-ILCl) based on the immobilization of benzotriazolium ionic liquid and further incorporation of samarium acetate or lanthanum acetate onto periodic mesoporous organosilica were afforded for the cycloaddition of CO2 and epoxides to produce cyclic carbonates. In consequence of the intramolecular synergistic effect between samarium sites of periodic mesoporous organosilica and homogeneously dispersed basic sites of ionic liquid, the powerful catalyst Sm-PMO-ILCl offered superior catalytic performance with ultra high yields and selectivities in the cycloaddition reaction without the addition of any solvent and cocatalyst. Moreover, the catalyst Sm-PMO-ILCl could be easily recovered by filtration and reused for at least five runs without any significant loss of its catalytic activity. Resumen. Se prepararon nuevos nano catalizadores (La-(Sm-PMO-ILC1) por la vía de inmovilización del líquido iónico benzotriazolium y adición se acetato de samario o acetato de lantano en organosilice mesoporosa. Los catalizadores se evaluaron en la ciclo adición de CO2 y epóxidos para producir carbonatos cíclicos. El efecto sinérgico intramolecular entre los sitios de samario de la organosilice y los sitios básicos del líquido iónico homogéneamente distribuidos inducen una alta actividad catalítica en el catalizador Sm-PMO-ILC1. Así, con este catalizador se obtuvo alta conversión y selectividad en la reacción de ciclo adición, sin agregar solvente ni co-catalizador. Además, el catalizador Sm-PMO-ILC1 podría recuperarse fácilmente por filtración y reusado por al menos 5 corridas sin pérdida significativa de su actividad catalítica.
