Abstract

The carbonylation of amines with propargylic alcohol using CO₂ as carbonyl source to yield N-substituted 4-methylene-2-oxazolidinones could efficiently proceed in ionic liquids, and various 4-methylene oxazolidinones with high yields could be obtained under relatively mild conditions. This result showed that ionic liquid might be an effective catalyst and reaction medium for the activation of CO₂, which also offered a new way to the chemical fixation of CO₂.
