Ceria nanoparticles as heterogeneous catalyst for CO2 fixation by ω-aminoalcohols

Abstract

In contrast to γ-Al₂O₃, TiO₂, ZrO₂, MgO and Y₂O₃, CeO₂ is a reusable catalyst for the reaction of CO₂ with ω-aminoalcohols to form cyclic carbamates; the highest yield (68%) was obtained for the preparation of N-alkyl 1,3-oxazolidin-2-ones from N-alkyl ethanolamines.
