Catalytic tricarbonylation of alkynes with palladium catalysts
A novel catalytic process of introducing three CO units into alkynes by palladium-catalyzed alkoxycarbonylation was developed. Based on the fundamental studies on the behavior of organopalladium complexes, mechanisms to account for the mono- and tricarbonylation processes are proposed.
