Imidazolium-based ionic liquids containing multipoint hydrogen bond donors as bifunctional organocatalysts for efficient cooperative conversion of CO₂ to cyclic carbonates

Abstract

Bifunctional imidazolium-based ILs possessing multipoint HBDs efficiently catalyze the cycloaddition reaction of CO 2 and epoxides at a significantly low loading to form cyclic carbonates with a wide scope of substrates.
