Using basic ILs as catalysts for the conversion of cheap, abundant, nontoxic, and renewable CO_2 into value-added organic carbonates is highly significant in view of environmental and economic issues. This review aims at giving a detailed overview on the recent advances on basic ILs promoted chemical transformation of CO_2 to cyclic and linear carbonates. The structures of various basic ILs, as well as the basic ILs promoted reactions for the transformation of CO_2 to organic carbonates are discussed in detail,including the reaction conditions, the yields of target products, the catalytic activities of basic ILs and the reaction mechanism.展开更多
