The loss of HF is one of the main fragmentation processes in the metastable molecular ions of fluorophenols and fluoroanilines. By investigation of D‐labelled compounds, it could be established that the eliminated HF molecule contains the hydroxylic or amino hydrogen atom. The other ring hydrogen atoms are not involved in the fragmentation. In order to rationalize this process, a "ring‐walk' mechanism of the fluorine atom is proposed.
