The Study for Synthesis of a Macromolecule Colyliform Ionic Liquid and Catalysis for the Multicomponent Reactions of Aryl-Oxazolidinones from CO2 with Epoxides and Aniline
Oxazolidinone is synthesized by the multicomponent reaction of epoxides,CO2 and amines,which is a route of great economic value and environmental benefit.Herein,a catalyst of macromolecule colyliform ionic liquid was synthesized.This catalyst showed highly effect for the cycloaddition of CO2 with epoxides and aniline to aryl-oxazolidinones.Under the optimization condition(150℃,1 MPa,15 h),the selectivity was 97.1%,yield of aryl-oxazolidinones could reach above 87.8%,and can be used for three times.
