Maleic anhydrides can be obtained in high yields by the PdCl 2 -catalyzed dicarbonylation of terminal acetylenes in H 2 O/dioxane. It is not necessary to add reoxidants to the reaction, but reoxidants can affect the yield and the rate. We also found that the rate decreased and only traces of maleic
## Abstract The productions of maleic diesters and maleic anhydrides depend on the effect of solvent and acidβbase in palladiumβcatalyzed dicarbonylation of terminal acetylenes. For primary and secondary alcohol in benzene, only maleic diesters were obtained stereospecifically from the dicarbonylat
