Abstract

Maleate diesters and maleic anhydrides can be synthesized respectively by using different type of alcohol in the palladium catalyzed dicarbonylation of terminal acetylene. In primary or second aliphatic alcohols, only α,β-unsaturated diesters were yielded. In tert-BuOH, maleic anhydrides were selectively synthesized.
