Other Notes:

Acidic amides are superior directing groups for promoting C-H activation reactions with both Pd(0)/PR₃ and Pd(II) catalysts.

Used in the Preparation of
• Lactams via palladium-catalyzed olefination of arylamides with benzylacrylate, followed by 1,4-conjugate addition
• N-(fluorinated aryl)benzamides as substrates for regioselective C-H amination reactions with O-benzoylhydroxylamines
• Substituted succinimides via palladium-catalyzed carbonylation of N-aryl amides
• N-aryl cyclopropanecarboxamide substrates and various amino acid ligands for palladium-catalyzed C-H activation of cyclopropanes
