The formation of [C9H10]+˙ ions by loss of a molecule of water from molecular ions of 3-phenylpropanol with lifetimes of 10−11 to 10−5 s

摘要: Field ionization kinetic experiments in conjunction with deuterium labelling have been shown that the molecular ions of 3-phenylpropanol lifetimes as short 10−11s lose a molecule water via specific 1,3 elimination. At times > two distinct hydrogen interchange processes appear to complete this reaction. One intechange involves benzylic and hydroxylic atoms starts elimination at shorter ion than other process which ortho also participate. Decomposing [C9H10]+˙ generated by from or direct various isomeric C9H10 compounds could not be distinguished adequately, illustrating isomerization either common structure set rapidly interconverting structures. A consideration energetics suggests threshold energies 1-phenylpropene indane type structures can formed. Arguments for latter obtained observation labile fluorine atom is present [M – H2O]+˙ 3-pentafluoro-phenylpropanol.
