Under atmospheric pressure, 4-(arylamino)methyl substituted ethylene carbonates were synthesized from the reaction of carbon dioxides (1 or 0.5 atm) with aromatic amine and 2-(bromomethyl)oxirane catalyzed by a ternary system of ZnBr2/K2CO3/[Bmim]Br, while [Bmim]Br (1-butyl-3-methyl-1H-imidazol-3-ium bromide) acted as both catalyst and solvent in the reaction. In the catalytic protocol, the products were isolated in good to excellent yields with good selectivity (up to 96%, total 15 examples). Various functional groups, such as -OMe, -F, -Cl, -Br, -I, -Me, -Et, -COMe and -CN were found tolerant in the reaction. The presence of a small amount of water and air in CO2 does not affect the catalytic activity, and the catalyst can be recycled.
