Synthesis of cyclic carbonates from CO sub(2) and epoxides catalyzed by low loadings of benzyl bromide/DMF at ambient pressure

Synthesis of cyclic carbonates from CO sub(2) and epoxides catalyzed by low loadings of benzyl bromide/DMF at ambient pressure

An efficient, metal-free catalytic system for the conversion of CO sub(2) and epoxides to cyclic carbonates under mild conditions with good-to-excellent yields (57-99%) was developed. A possible reaction mechanism involving the electrophilic activation of epoxides by benzyl cations and nucleophilic...

Zusammenfassung:An efficient, metal-free catalytic system for the conversion of CO sub(2) and epoxides to cyclic carbonates under mild conditions with good-to-excellent yields (57-99%) was developed. A possible reaction mechanism involving the electrophilic activation of epoxides by benzyl cations and nucleophilic activation of CO sub(2) by DMF is proposed.
