Biaryl-like CATPHOS diphosphines via double diels-alder cycloaddition between 1,4-bis(diphenylphosphinoyl)buta-1,3-diyne and anthracenes: Efficient ligands for the palladium-catalyzed amination of aromatic bromides and α-arylation of ketones

Academic Article

Abstract

  • A mixture of palladium(0) and CATPHOS, the 1,3-butadiene-bridged diphosphine generated via double Diels-Alder cycloaddition between bis(diphenylphosphinoyl)buta-1,3-diyne and anthracene, catalyzes the amination of a range of aromatic bromides as well as the α-arylation of ketones, giving conversions that either rival or exceed those obtained with BINAP. © 2008 American Chemical Society.
