摘要：

We used two-color resonant two-photon ionization combined with time-of-flight mass spectrometry to study nucleophilic ipso-substitution reactions with halobenzenes radical cations. Molecular clusters serve as microscopic test tubes to tackle the reactivity problem of solvated radical cations. The reaction paths - van der Waals fragmentation and chemical reaction - could be energetically separated. The substitution reactions turned out to be nearly activationless. The particularities of the excitation process are discussed.
