摘要：

To realize a true green CO2 utilization process, the development of a catalytic system having no toxic components is essential. Herein, tertiary amines without any metal or halide additives are introduced as simple and green organocatalysts to activate CO2 and insert into epoxides, producing synthetically important cyclic carbonates. Among those amines, diamine such as N,N,N',N'-tetraethylethylenediamine exhibited a moderate to excellent efficiency. This new class of organocatalyst which does not have any toxic metals and halides is easy to handle and only requires as low as a 0.1 mol% loading. Additional favorable features include solvent free conditions and broad substrate scopes. (C) 2016 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
