## Abstract Carbon dioxide was found as a selective agent to promote the palladium‐catalyzed cyclotrimerization of alkynes in water. Both aryl and alkylacetylenes afforded the corresponding cyclotrimerization products regioselectively in high yields using PdCl~2~, CuCl~2~, and CO~2~ as the catalyti
