Development of a Catalytic Aromatic Decarboxylation Reaction
摘要:
A palladium-catalyzed aromatic decarboxylation reaction has been developed. With electron-rich aromatic acids, the reaction proceeds efficiently under fairly mild conditions in good yields. The method was useful with complex functionalized substrates containing hindered carboxylic acids.

reaction. The first step, decarboxylative palladation, is proposed to occur through an intramolecular electrophilic palladation pathway, which is supported by computational and mechanism studies. In contrast to the reverse reaction (C–H insertion), the data support an electrophilicaromaticsubstitutionmechanism involving a stepwise intramolecular protonation sequence for the protodepalladation portion of
