Synthesis of oxazolidinones by efficient fixation of atmospheric CO2 with propargylic amines by using a silver/1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) Dual-catalyst system.

This'll fix it: efficient fixation of atmospheric CO(2) has been achieved by the reaction of propargylic amines with a silver/DBU dual-catalyst system. Various oxazolidinones were synthesized in moderate to good yields by using substituted propargylic amines.
