文摘

Using 1-butyl-3-methyl-imidazolium bromide (BMIMBr) as the supporting electrolyte and magnesium as the sacrificial anode, a new and highly efficient electrochemically catalytic route was developed for the synthesis of cyclic carbonates from epoxides and CO₂. Based on the cooperative action of BMIMBr and an electrogenerated magnesium salt obtained under a N₂ atmosphere, CO₂ reacted with a wide range of epoxides to readily generate cyclic carbonates in moderate to excellent yields under mild conditions.
