Other Group V Donor Complexes

In contrast, reaction of PPh, or PfOMe), results in disproportionation at ratios 1  

If the ratio phosphine Hg is 1, then all except PF3 undergo disproportionation Hgi +n phos Hg(phos) + Hg 

Reactions of AsPhj, SbPhj, R3PS, or RjPSe with H (AsF )2 yield insoluble 2 1 adducts which i.r. studies show still to contain the ion. 1 1 complexes between MX2 (M = Cd or Hg X = Cl or Br) and the phosphine-phosphine oxide ligands Ph2P(0)CHRPPh2 (R = H, CH3, or Pr ) have been characterized by n.m.r. spectroscopy.
