The reagent system HF/SbF5/CCl4 generates trichloromethyl cations reacting as a strong hydride acceptor. Thus, application of the system to cyclohexanones (I) and (IV) or steroidal enones (cf. (VII)) results in formation of the corresponding dehydrogenation products. -

## Abstract The structures of the major adduct ions formed in ammonia chemical ionization of thirteen aliphatic and aromatic ketones have been studied by mass analysed ion kinetic energy spectrometry. The [M+NH~3~+H]^+^ ion is shown to have a protonated carbinolamine structure, [M+2NH~3~+H]^+^ to b
