S. Martrenchardbarra et al., CHEMICAL-REACTIVITY IN MICROSCOPIC SYSTEMS - THE NUCLEOPHILIC-SUBSTITUTION OF HALOGENATED BENZENE IONS BY AMMONIA STUDIED IN MOLECULAR CLUSTERS, Journal of physical chemistry, 99(37), 1995, pp. 13716-13730
The reactivity of small dihalogenated benzene ions clustered with ammo
nia has been investigated through mass-selected two-color two-photon i
onization. Two reaction channels are evidenced: halogen elimination an
d hydrogen halide elimination. Appearance thresholds of the different
reactive paths have been measured as well as the kinetics of the react
ions. From these measurements, a new reactive scheme is proposed.
