Applicazioni

Diphenylphosphine oxide can be used as a coupling partner to prepare various organophosphorus compounds via cross-coupling reaction with aryl halides in the presence of Ni/Zn catalyst.
It can also be used as a reactant to synthesize:
  • Diphenyl(2-phenyl-2H-indazol-3-yl)phosphine oxide derivatives by phosphonylation of 2H-indazoles using rose bengal as a catalyst.
  • Alkenyldiphenylphosphine oxides by hydrophosphinylation of terminal alkynes in the presence of transition metal catalysts.
  • Diphenylphosphino-containing chiral ligands for asymmetric catalytic reactions via Pd-catalyzed coupling reaction with aryl triflates.
  • Triarylphosphine oxides and Horner-Wittig reagents.
