Abstract

In a palladium-catalyzed oxidative carbonylation reaction for the synthesis of phthalimides, an imine and H₂O, which are generated in situ from the condensation of aldehyde and amine, serve as self-sufficient directing group and nucleophile, respectively. This method provides rapid access to phthalimides starting from readily available materials with high atom- and step-economy in a one-pot manner.
