Dissociative ionization of aryl-substituted vinyl bromides in the gas phase: Experimental and computational evidence for the formation of stable α-arylvinyl cations both by direct means and spontaneous exothermic isomerization of unstable isomeric ions

The kinetic energy release T which accompanies the Br· loss from ionized (E)- and (Z)-β-bromostyrenes (5 and 6) in the gas phase is higher by 0.7 ± 0.03 kcal mol^-1 than that from the molecular ion of α-bromostyrene (4). Together with both colli
