A series of tetrahaloindate(III)-based ionic liquids (ILs) have been
produced by microwave-assisted synthesis. These ionic liquids have been examined
as catalyst
in the reaction of CO2 with a various epoxides to give cyclic
carbonates. Tetrahaloindate(III)-based ILs are found to
exhibit high catalytic activities. The effects of a variety of parameters (temperature, pressure, molar ratio of propylene oxide to catalyst),
the mechanism, and the
significant role of H-bonding interactions in the coupling
reactions are discussed.
