Application

Bis(pentafluorophenyl)phenylphosphine serves as a privileged ligand in palladium-catalyzed cross-coupling reactions (e.g., Suzuki-Miyaura, Heck) due to its strong ??-donor/??-acceptor properties. Its electron-deficient fluorinated aryl groups enhance oxidative addition kinetics in metal complexes while improving catalyst stability. The compound is also employed in the synthesis of luminescent materials and as a precursor for phosphorus-containing polymers with high thermal stability. Researchers utilize it to modulate steric and electronic environments in homogeneous catalysis.
