Highly selectivesynthesis of 2-oxazolidinone from CO2 and 2-aminoethanol inacetonitrile solvent was achieved over heterogeneous CeO2 catalyst.Yield of 2-oxazolidinone reached 97% at 97% 2-aminoethanol conversion with>99% 2-aminoethanol-based selectivity in the optimized reaction conditions.Various aminoalcohols were converted to the corresponding cyclic carbamates inhigh yields (82% to >99%) with high selectivity (91% to >99%). Complete retentionof configuration for the aminoalcohols having a chiral center at the a-positionof the hydroxyl group was also achieved. In addition, kinetics and FTIR studiessuggested the reaction mechanism over CeO2.
