Fast-atom bombardment mass spectrometry of eight omega-hydroxyalkyltriphenylphosphonium bromides

The mass spectrometric behaviour of eight omega-hydroxyalkyltriphenylphosphonium bromides was studied,vith the aid of mass-analysed ion kinetic energy spectrometry and high resolution data under fast-atom bombardment ionization, The fragmentation mechanism of a series of fragment ions at m/z 275, 289, 303,... is described in detail, All the compounds show [2M+Br](+) ions because of association by hydrogen (C) 1997 by John Wiley & Sons, Ltd.Chemistry, AnalyticalSpectroscopySCI(E)3ARTICLE151728-17301
