It is shown by ion cyclotron resonance measurements that ion/molecule reactions, leading to substitution or reduction product ions from chloro‐ and nitrobenzene with the title amines, are those between the molecular ions [RNH 2 ] + or [C 6 H 5 X] + ˙ and their respective counterparts C 6 H 5 X or RNH 2 . The protonated reagent gas ions [RNH 3 ] + are not involved in these reactions. In the case of nitrobenzene, adduct ions [C 6 H 5 NO 2 ·RNH 3 ] + do not decompose within the time scale of the measurements. The results obtained are compared with those found under chemical ionization conditions.
