  Numerous bifunctional organocatalysts were synthesized and tested for the atom‐efficient addition of carbon dioxide and epoxides to produce cyclic carbonates. These catalysts are based on phosphonium salts containing an alcohol moiety in the side chain for substrate activation through hydrogen bonding. In the model reaction, converting 1,2‐butylene oxide with CO2, 19 catalysts were tested to determine

  合成了许多双功能有机催化剂，并测试了碳和环氧化物的原子效率加成反应，以生产环状碳酸酯。这些催化剂基于在侧链中包含醇部分的phospho盐，用于通过氢键活化底物。在模型反应中，测试了用CO 2转化1,2-环氧丁烷，19种催化剂以确定结构与活性之间的关系。总共有28种环氧化合物被CO 2转化得到相应的环状碳酸酯，产率最高可达99％。即使在45°C时，活性最高的催化剂也能够以高收率选择性地生产环状碳酸酯。在硅胶上简单过滤后，通常以分析纯的形式获得碳酸盐。这种单组分催化剂体系可在纯净和温和的反应条件下运行，并能耐受多个有用的部分。

  Disclosed is a process for producing ethylene glycol catalyzed by an ionic liquid, characterized in that the process includes the following three steps: (a) a carbonylation step of ethylene oxide and CO 2 catalyzed by an ionic liquid composite catalyst comprising a hydroxyl functionalized ionic liquid and an alkali metal salt under an aqueous condition to produce ethylene carbonate and ethylene glycol; (b) a hydrolysis step of reacting the reaction solution containing ethylene carbonate and the ionic liquid composite catalyst obtained in step (a) with water to produce ethylene glycol; (c) a purification step of dehydrating and refining ethylene glycol from the aqueous solution containing ethylene glycol and the catalyst produced in step (b). The present process has the following advantages: the catalyst has high activity, high suitability, and good stability, the reaction condition is wild, the conversion of ethylene oxide is high, the selectivity of ethylene glycol is high, and the process is simple.

  was verified by solid-state NMR and FT-IR. SEM and EDX measurements revealed a homogeneous distribution of the phosphonium salt on the particle surface. This catalyst facilitated the addition of CO2 to epoxides under mild conditions. The evaluation of the substrate scope and the catalyst recycling were combined in one set of experiments. In 15 consecutive runs, the synthesis of 12 cyclic carbonates in

  制备了几种双官能phospho盐催化剂并将其固定在二氧化硅和聚苯乙烯载体上。将固定的体系与其均相类似物在环状碳酸酯合成中进行了比较。有趣的是，在某些情况下，固定化催化剂的活性更高。活性最高的系统是负载在二氧化硅表面的酚官能化phospho盐。solid单元与二氧化硅的共价键通过固态NMR和FT-IR验证。SEM和EDX测量表明phospho盐在颗粒表面上均匀分布。该催化剂促进了CO 2的添加在温和的条件下会氧化成环氧化物。在一组实验中结合了对底物范围的评估和催化剂的再循环。在连续15次运行中，合成了12种环状碳酸酯，产率高达98％。循环实验后对催化剂的研究表明，原始阴离子（溴化物）的损失以及of单元的数量减少，这解释了在循环实验过程中观察到的催化剂失活。
