  Mn(III)(salen)-catalyzed synthesis of cyclic organic carbonates from propylene and styrene oxide in “supercritical” CO2

  摘要：

  Various homogeneous and immobilized manganese-salen complexes were synthesized and tested as catalysts for the formation of cyclic organic carbonates from two liquid epoxides (propylene oxide and styrene oxide) and CO2, which served as reactant and solvent. Reaction rates in terms of turnover frequencies up to 255 mol(product) mol(Mn)(-1) h(-1) at 98% selectivity were achieved by optimizing the salen ligand as well as the reaction temperature and CO2 pressure. The reaction rates did not only strongly depend on the kind of salen ligand, the phase behaviour, and the reaction conditions but significant differences were also observed between the epoxide reactants. In addition, two different and simple ways for the immobilization of Mn-salen complexes were examined, among which one led to a highly active, stable and reusable heterogeneized catalyst. In this heterogeneous catalyst the salen ligand was covalently bound to the silica surface and showed low deactivation and almost no leaching of Mn during repetitive use. A coordinatively bound Mn-salen complex resulted in a high loading of the Mn-salen complex on a specially modified silica surface, but was not stable enough. Furthermore, phase behaviour studies and ATR-IR spectroscopic investigations on the product formation are reported that gave further insight into this catalytic reaction taking place at elevated pressure.

  Salen 修饰的周期性介孔有机二氧化硅：从金属辅助环氧化到无金属 CO2 插入

  摘要：

  我们使用光引发的硫醇-烯点击反应将 salen 配体点击到硫醇-乙烷桥连的周期性介孔有机硅 (Salen-PMO) 上。该过程在 PMO 材料上产生了共价键合的 salen 配体。最终的 BET 表面积为 511 m 2 /g，孔径直径约为 7 nm。功能化的 PMO 材料在 273 K 和 1 bar 下表现出优异的二氧化碳吸收能力，为 1.29 mmol/g。更重要的是，通过协调一个 MoO 2 2+络合物到Salen-PMO材料上，我们获得了一种对环己烯环氧化具有良好催化性能的多相催化剂。该催化剂具有高度可重复使用性，因为在至少四次运行中未观察到其活性降低（转化率为 99%）。最后，不含金属的Salen-PMO在CO 2环加成成环氧化物时表现出优异的催化性能。获得的结果清楚地证明了 Salen-PMO 材料的多功能性，不仅可以作为无金属催化剂，而且可以作为固定金属配合物用于特定催化应
