Chemical Properties

Formula Weight
Melting point


The reaction of (pentafluorophenyl)diphenylphosphine with C-ethoxycarbonyl-(p-methoxyphenyl) nitrile imine was used to synthesize [2,3,4,5-tetrafluoro-6-(p- methoxyphenylamino)phenyl]diphenylphosphine oxide whose reduction with trichlorosilane. the reactions of (pentafluorophenyl)diphenylphosphine and bis(penta- fluorophenyl)(phenyl)phosphine with nitrilimines (Housgen 1,3-dipoles) involves two-stage cycloaddi- tion and leads to formation of sufficiently stable fluorophosphoranes.


Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.
