Carbon and hydrogen scrambling in the ions C(9+n)H(9+2n)+. Rearrangements of cyclooctatetraene derivatives

Abstract

Carbon and hydrogen scrambling occurs either prior to, or during, the decompositions of the ions C9H9+, CllH13+, and C12H15+ in the first field-free region of the mass spectrometer. The ions may be produced from various substrates, and the decompositions of CllH13+ may be interpreted in terms of a decomposing ion in which some, but not all, of the C-H bonds have broken and reformed. The ions C9H9+ and C10H11+ may be produced by complex hydrogen rearrangement in the side-chain of particular bromo-and hydroxy-alkylcyclooctatetraene derivatives.
