其他說明

Acidic amides are superior directing groups for promoting C-H activation reactions with both Pd(0)/PR3 and Pd(II) catalysts.[1]

Used in the Preparation of
  • Lactams via palladium-catalyzed olefination of arylamides with benzylacrylate, followed by 1,4-conjugate addition[2]
  • N-(fluorinated aryl)benzamides as substrates for regioselective C-H amination reactions with O-benzoylhydroxylamines[3]
  • Substituted succinimides via palladium-catalyzed carbonylation of N-aryl amides[4]
  • N-aryl cyclopropanecarboxamide substrates and various amino acid ligands for palladium-catalyzed C-H activation of cyclopropanes[5]

Pd(II)-catalyzed β-C(sp(3))-H carbonylation of N-arylamides under CO (1 atm) has been achieved. Following amide-directed C(sp(3))-H cleavage and insertion of CO into the resulting [Pd(II)-C(sp(3))] bond, intramolecular C-N reductive elimination gave the corresponding succinimides, which could be readily converted to 1,4-dicarbonyl

C-H amination of N-aryl benzamides with O-benzoyl hydroxylamines has been achieved with either Pd(II) or Pd(0) catalysts. Furthermore, we demonstrate that secondary amines can be directly used with benzoyl peroxide in a one-pot procedure that proceeds via the in situ

Systematic ligand development has led to the identification of novel mono-N-protected amino acid ligands for Pd(II)-catalyzed enantioselective C-H activation of cyclopropanes. A diverse range of organoboron reagents can be used as coupling partners, and the reaction proceeds under mild conditions.
