Abstract:

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.
