Lactone enol cation-radicals: Gas-phase generation, structure, energetics, and reactivity of the ionized enol of butane-4-lactone

The cation-radical of 2-hydroxyoxol-2-ene (1+?) represents the first lactone enol ion whose structure and gas-phase ion chemistry have been studied by experiment and theory. Ion 1+? was generated by the McLafferty rearrangement in ionized 2-acetylbutane-4-lactone and characterized by accurate mass measurements, isotope labeling, metastable ion and collisionally activated dissociation (CAD) spectra. Metastable 1+? undergoes competitive losses of H-4 and CO that show interesting deuterium and 13C isotope effects. The elimination of CO from metastable 1+? shows a bimodal distribution of kinetic energy release and produces ?CH2CH2CH=OH+ (14+?) and CH3CH=CHOH+? (15+?) in ratios which are subject to deuterium isotope effects. Ab initio calculations at the G2(MP2) level of theory show that 1+? is 105 kJ mol-1 more stable than its oxo form, [butane-4-lactonel]+?(2+?). The elimination of CO from 1+? involves multiple isomerizations by hydrogen migrations and proceeds through ion-molecule complexes of CO with 14+? and 15+?. In addition, CO is calculated to catalyze an exothermic isomerization 14+? → 15+? in the ion-molecule complexes. Multiple consecutive hydrogen migrations in metastable 1+?, as modeled by RRKM calculations on the G2(MP2) potential energy surface, explain the unusual deuterium kinetic isotope effects on the CO elimination.
