A novel copper metal–organic framework catalyst for the highly efficient conversion of CO 2 with propargylic amines

The rapid increase in atmospheric carbon dioxide has resulted in the greenhouse effect. Hence, carbon dioxide capture and further fixation into valuable chemical products are particularly important for reducing atmospheric carbon dioxide concentrations. In this direction, a novel copper-based metal three-dimensional framework, Cu-TSP, was assembled from tripod ligands containing thiourea groups; this heterogeneous material can efficiently catalyze the reaction of propargylic amines and carbon dioxide to synthesize 2-oxazolidinones, and the recyclability and high conversion rates demonstrate the broad potential applications of this designed material as a π-activated catalyst in the chemical industry.
