Cationic Polymers Bearing Quaternary Ammonium Groups-Catalyzed CO2 Fixation with Epoxides

Tiffner, Maximilian ; Häring, Marleen ; Díaz, David Díaz ; Waser, Mario


A series of cationic polymers containing quaternary ammonium groups turned out to be powerful catalysts for the CO2-fixation of epoxides under an atmospheric pressure of CO2 at elevated temperature. A variety of differently substituted aromatic and aliphatic epoxides were well tolerated and the polymeric catalysts could easily be recovered by a simple filtration and reused without any loss in catalytic activity.
