Notes: The 70 eV electron-impact low resolution spectra of Me3SiPPh2, (Me3Si)3SiPPh2, and (Me3Si)2(Me)SiP(Me)(Ph) were investigated. The migration of two phenyl groups from phosphorous to a silicon site was observed and the unimolecular mass-analysed ion kinetic energy spectra indicated that the migration occurred in [M — CH3]+ ions rather than in M+· ions. The benzene eliminations from the M+· and [M — CH3]+ ions of Me3SiPPh2 were observed not in the EI spectrum, but in their MIKE spectra.
