基　　金：The authors are grateful to the National Natural Science Foundation of China(Nos.21003133 and 20932002);Ministry of Science and Technology of China(Grant No.2009CB930802);Chinese Academy of Sciences(Grant No.KJCX2.YW.H16). 摘　　要：The synthesis of cyclic carbonates or dimethyl carbonate(DMC)using CO_(2) as a building block is a very interesting topic.In this work,we found that the metalorganic framework-5(MOF-5)/KI was an active and a selective catalytic system for the synthesis of cyclic carbonates from CO_(2) and epoxides,and MOF-5/KI/K_(2)CO_(3) was efficient for the preparation of DMC from CO_(2),propylene,and methanol by a sequential route.The impacts of temperature,pressure,and reaction time length on the reactions were investigated,and the mechanism of the reactions is proposed on the basis of the experimental results. 关键词：carbon dioxide cyclic carbonates dimethyl carbonate(DMC) metal-organic framework-5(MOF-5) sequential route propylene oxide
