The reaction of N-trimethylsilylphosphinineimines, Me3SiN=PR1R2R3 (R1, R2, and R3=hydrocarbon or NMe2 group) with the fluorophosphoranes, MePF4, PhPF4, and Me2PF3 has furnished fluorophosphineiminophosphonium organofluorophosphates, involving the anions, - (R=Me, Ph) or -, respectively.The characterization of these salts by 1H, 19F, and 31P n.m.r. spectroscopy is descriebed.The n.m.r. parameters are discussed in term of electronic structure.The 2JPP coupling constant was determined to be positive by triple resonance experiments on two of the compounds.

Tri-n-butylfluorophosphonium bromide and N-trimethylsilylphosphinimines R3P=N-SiMe3 react with formation of trimethylsilyl bromide and fluoride and mixed phosphiniminophosphonium bromides/fluorides, n3P-N=PR3>Br/F.Metathetical reactions with sodium iodide, ammonium hexafluorophosphate and potassium perchlorate yield the corresponding phosphiniminophosphonium iodides, hexafluorophosphates and perchlorates, respectively.The cations n3P-N=PR3>(+) behave as phase-transfer agents.In the presence of these cations permanganate anion is transferred from aqueous solu tions into benzene. - Key words: Silylphosphinimine; Tri-n-butylfluorophosphonium Bromide, Metathesis Reactions
