Application

Ligand used in a Pd-catalyzed Suzuki aryl-aryl coupling leading to benzodioxepines.
DavePhos may be used as a ligand in the following reactions:
  • Palladium catalyzed sp3 arylation of 2-substituted-N-iminopyridinium ylides with different aryl chlorides to yield functionalized pyridines.
  • Preparation of functionalized benzylic sulfones via palladium-catalyzed Negishi cross-coupling between alkyl sulfones and aryl halides.
  • C-C Coupling of 3-haloquinolines with aryl sulfinates via palladium-catalyzed desulfitative arylation to form the corresponding biaryl compounds.
Useful ligand for Pd-catalyzed C-N bond formation; amination of aryl halides containing hydroxyl, amide, or enolizable ketones.
