Anionic rearrangement in the gas phase. The collision-induced loss of carbon monoxide from deprotonated pyruvates and hydroxyacetates
Abstract
Deprotonated pyruvates and hydroxyacetates, upon collisional activation, undergo loss of CO by anionic rearrangement through alkoxycarbonyl ion complexes, e.g. [graphic omitted] and [graphic omitted] Such processes have been substantiated by labelling (2H, 13C), and production studies.
