Cationic Polymers Bearing Quaternary Ammonium Groups-Catalyzed CO 2 Fixation with Epoxides

摘要

A series of cationic polymers containing quaternary ammonium groups turned out to be powerful catalysts for the CO~(2)-fixation of epoxides under an atmospheric pressure of CO~(2)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.
