AbstractStereoelectronic factors allow facile Cl˙ atom loss from the exo‐6‐chloro‐2‐norbornanone radical cation but not from the endo‐6‐epimer. The predominant primary reaction in the endo‐6 and in the exo‐5 and endo‐5 compounds is HCl elimination. While CI˙ elimination occurs with skeletal reorganization, HCl loss, at least in part, does not. The 5‐chloro isomers undergo a regiospecific McLafferty rearrangement which occurs relatively slowly in competition with Cl˙ and HCl loss. The use of energy‐resolved forms of tandem mass spectrometry provides considerable detail regarding the unimolecular fragmentations of these gaseous ions.
