Highly efficient neutral and ionic imidazole-based organocatalysts have been developed for the synthesis of cyclic carbonates from epoxides and carbon dioxide. The ionic derivatives performed as bifunctional catalysts and exhibited improved activity for the fixation of CO₂ compared to the neutral compounds. Mechanistic studies revealed that the hydroxyl group promoted the activation of the epoxide facilitating the epoxide ring-opening by nucleophilic attack of the iodide.

研发用于将CO ₂固定为环状碳酸酯的含羟基咪唑有机催化剂†

已经开发出高效的基于中性和离子咪唑的有机催化剂，用于由环氧化物和二氧化碳合成环状碳酸酯。与中性化合物相比，离子衍生物作为双功能催化剂发挥了作用，并表现出提高的CO ₂固定活性。机理研究表明，羟基通过碘的亲核攻击促进了环氧化物的活化，从而促进了环氧化物的开环。
