insertion of CO2 to form the active silyl formats, thereby leading to excellent catalytic performance at a low catalyst loading. Furthermore, the bifunctional Zn(salen) complexes, with two imidazolium‐based ionic‐liquid (IL) units at the 3,3′‐position of salen ligand, acted as intramolecularly cooperative catalysts, and the solvent‐regulated separation resulted in facile catalyst recycling and reuse.
