| Application: | 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. • Alkenyldiphenylphosphin • Diphenylphosphino-conta • Triarylphosphine oxides and Horner-Wittig reagents. |
