Phosphorus–fluorine chemistry. Part XX. Redox disproportionation of difluorophosphines, RPF2, with electronegative substituents R

Abstract

Difluorophosphines, RPF₂, containing the electronegative substituents, R = CF₃ and C₆H₅, will undergo redox disproportionation with formation of tetrafluorophosphoranes and cyclopolyphosphines, in accord with the overall equation 10 RPF₂→ 5 RPF₄+(RP)_n(n= 4, 5 for R = CF₃; n= 5 for R = C₆H₅). The identity of the products, all previously known, was established by comparison of their physical properties (n.m.r. and mass spectra, i.r. spectra, X-ray powder diagram, etc.) to those of the authentic compounds.
