The metal-catalyzed carboxylation of propargylamines with aerial CO2 at room temperature to form 5-methyleneoxazolidin-2-one derivatives has been developed. In this reaction, the catalyst [Au(dpbF)]X featuring a Z-type ligand gave the best results, presumably due to the σ-acceptance of the borane atom.
NHC-Gold(I) complexes as effective catalysts for the carboxylative cyclization of propargylamines with carbon dioxide

NHC-gold(I) complexes promote carboxylative cyclization of a range of propargylic amines to afford (Z)-5-alkylidene-1,3-oxazolidin-2-ones in methanol under neutral and mild conditions. The highly active and robust catalyst permits CO2 utilization under a mixed gas atmosphere containing CO or H 2. As a key intermediate, a new alkenylgold(I) complex was successfully identified from a stoichiometric reaction of Au(OH)(IPr) and 1-methylamino-2-butyne in THF. The methanol solvent influences the formation of catalytically active cationic gold species and facilitates protodeauration from the alkenylgold complex to release the cyclic urethane product due to in situ generation of methylcarbonic acid in the presence of CO2.
Binuclear Tridentate Hemilabile Copper(I) Catalysts for Utilization of CO2into Oxazolidinones from Propargylic Amines

Four binuclear tridentate copper(I) complexes were synthesized based on the trans effect of the hybrid ligands. The catalytic performance and behavior of the prepared copper(I) complexes were evaluated in the carboxylative cyclization of propargylic amine
Valorization of CO2: Preparation of 2-Oxazolidinones by Metal-Ligand Cooperative Catalysis with SCS Indenediide Pd Complexes

The capture and utilization of CO2 to prepare high-value compounds is very attractive chemically and highly desirable socially. Indenediide-based Pd SCS pincer complexes are shown here to promote the carboxylative cyclization of propargylamines
