  • Selenenylphosphonium ions as intermediates in the phosphane assisted methylation of elemental selenium
    Pietschnig, Rudolf ...
    (Methylseleno)tri-n-butylphosphonium iodide has been prepared and was characterized by heteronuclear NMR spectra, ESI-MS and chemical analysis. The charge distribution and bond situation of its ... cation has been explored by quantum chemical methods at Hartree- Fock, DFT(B3LYP) and MP2 level. The results support a description as a selenenylphosphonium ion rather than as a donor stabilized selenenium ion. Treatment with methyl iodide yields Me3Se+I-, the crystal structure of which was reinvestigated.
