Ion cyclotron resonance spectroscopy has been used to study reactions of the silicenium ions, Me2HSiO S +iMeR (R = H and Me), generated from sym-tetramethyldisiloxane in the gas phase. These silicenium ions react with neutral sym-tetramethyldisiloxane by an addition-elimination process, to form the homologous silicenium ions, H(Me2SiO ) +nSiMeR (n = 2 and 3). Analogous addition-elimination products, MeO(Me2SiO)nSiMeR, are derived from their reaction with methanol. Bimolecular adducts are observed in the presence of benzene and anisole, while oxygen abstraction occurs in the presence of anisole and acetone.
