General description

4-(Diphenylphosphino)benzoic acid is a phosphine ligand that is employed in palladium-catalyzed cross-coupling and Suzuki cross-coupling reactions.

Application

4-(Diphenylphosphino)benzoic acid can be used as a ligand in the synthesis of:
  • Organostannoxane-supported palladium nanoparticles. The resulting catalysts show high activity and selectivity in Suzuki-coupling reactions.
  • Polymetallic ruthenium-zinc complex catalyst for the hydrogenation of levulinic acid to γ-valerolactone.
