The Reactions of Enol Radical Cations with Propene in the Gas Phase
Philippe Mourgues, Candida Monteiro, Henri E. Audier and Steen Hammerum, Org. Mass Spectrom., 25, 389 (1990)
The addition of enol radical cations to gaseous propene molecules
provides a gas-phase synthesis of the distonic ions that are
formed as intermediates
in the McLafferty rearrangement of aldehyde, ketone and carboxylic
acid radical cations.
