Reaction of Ar*P=PNR2 (Ar*=2,4,6-But 3C6H2) with CF3SO3H in the presence of triphenylphosphane in CH2Cl2 produces the isolable salt [Ar*PP(PPh3)]+ [CF3SO 3]- which is characterized by X-ray crystallography; the triphenylphosphane ligand of [Ar*PP(PPh3)]+ readily participates in nucleophilic substitution reactions affording a novel entry to donor-stabilized phosphanetriylphosphonium cations and P-functionalized diphosphenes.
