Über die Bildung der Jodphosphine PH2J und PHJ2 aus Phosphin und PJ3, P2J4 bzw. J2

The iodophosphines PH₂J and PHJ₂ are formed by the reaction of PH₃ with PJ₃, P₂J₄ or J₂ respectively. They are stable only in equilibria mixtures together with PH₃, PJ₃ and P₂J₄ in the presence of HJ. H-NMR-spectra: PHJ₂ doublett ?5,03 ppm, J_{P? H} = 145 Hz, PH₂J doublett ?2,95 ppm, J_{P? H} = 168 Hz. P-NMR spectra: PHJ₂ doublett +9 ppm, J_{P? H} = 145 Hz, PH₂J triplett +156 ppm, J_{P? H} = 168 Hz. The IR-spectra of PH₂J and PHJ₂ are reported.
