Mass spectra of organogermanes

Abstract

The electron-impact induced fragmentation of the organogermanes R₄Ge (R = H, Me, Et, Buⁱ, Ph, PhCH₂, and p-tolyl), R¹₃GeR²(R¹= Ph and R²= Et, H; R¹= PhCH₂ and R²= Et), R₆Ge₂(R = Buⁱ, PhCH₂), (PhCH₂)₂GeMe₂, Ph₆Ge₂O, and Me₃GeCl has been studied at 70 eV under high resolution, and that of the organogermanes (o,m-tolyl)₄Ge, Ph₃GeX (X = Me, PhCH₂, Cl, Br, and I), R₆Ge₂(R = Et, Ph, m-tolyl), (PhCH₂)₃GeH, Me₃GeH, and GeCl₄ at low resolution. Almost all the ion-current is carried by metal-containing ions and in general the most favoured fragmentation processes are those leading to even-electron ions.
