The Formation of +. from 1-Hepten-3-ol
McAdoo, David J.,Hudson, Charles E.
, p. 294 - 296 (1981)
The +. ion in the mass spectrum of 1-hepten-3-ol is shown to be by collisional activation spectra, appearence energies and comparison of the ratio of the intensities of metastable decomposition. (C4H8O)+. appears to be formed by rearrangement of ionized 1-hepten-3-ol to followed by γ-hydrogen rearrangement-β-cleavage.
Intermediacy of ion neutral complexes in the fragmentation of short-chain dialkyl sulfides
Filsak,Budzikiewicz
, p. 601 - 610 (2007/10/03)
The main fragmentation processes after electron ionization of butyl methyl and butyl ethyl sulfides are rationalized by the intermediacy of the ion neutral complex [RSH · methylcyclopropane](+·) as demonstrated by extensive labeling and collision activation studies.
A McLafferty Rearrangement in an Even-electron System: C3H6 Elimination from the α-Cleavage Product of Tri-n-butylamine
Budzikiewicz, Herbert,Bold, Peter
, p. 709 - 712 (2007/10/02)
It is shown by deuterium labelling, linked-scan measurements and collision activation that the .>+ (α-cleavage) ion in the electron impact ionization spectrum of tributylamine loses C3H6 with transfer of one hydrogen specifically from the γ-position.The experimental data point towards a mechanism which involves the intermediate formation of a distonic diradical ion from an excited α-cleavage ion which the eliminates the neutral alkene.
