Palladium-Catalyzed Aromatic Esterification of Aldehydes with Organoboronic Acids and Molecular Oxygen

A palladium-catalyzed aromatic esterification reaction of aldehydes with arylboronic acids under an air atmosphere was achieved that tolerates many functional groups and provides aryL benzoate derivatives with yields ranging from moderate to good.

Abstract

A palladium-catalyzed aromatic esterification reaction of aldehydes with arylboronic acids under an air atmosphere was achieved. This reaction tolerates many functional groups and provides aryl benzoate derivatives with yields ranging from moderate to good. Dioxygen takes part in the reaction and is crucial for this transformation.
