It remains a great challenge to convert CO 2 into high value‐added products under ambient pressure. Herein, an efficient dual‐component catalytic system, i. e., Ag(I)/(C 2 H 5 ) 4 NCl was developed for the synthesis of various β‐oxopropylcarbamates via one‐pot three‐component coupling of CO 2 , secondary amines and propargylic alcohols under atmospheric pressure. Besides, the strategy avoided the use of any additional ligand and basic species, and excellent selectivity was achieved with a yield of up to 98%. Additionally, 13 C carbonyl ‐labeled and control experiments were carefully performed to demonstrate the mechanism. Notably, this new method was also applied efficiently in quantitative chemical fixation of CO 2 , i. e., the two‐component reaction of propargylic alcohols and ammonium carbamates.
