A dual functionalized ionic liquid catalytic system was developed for the reaction between CO2 and propargylic alcohols, and exhibited excellent performance and good reusability, even under a low concentration of CO2 in a gram-scale reaction.
Multilayered covalently supported ionic liquid catalysts achieve excellent TON and productivity in the reaction of CO2 with various epoxides to produce cyclic carbonates.
Highly efficient synthesis of alkylidene cyclic carbonates from low concentration CO2 using hydroxyl and azolate dual functionalized ionic liquids
