Some simple rules for predicting the transfer of endo hydrogens in the mass spectra of norbornane carbonyl derivatives are proposed. Transfers from C‐6 to C‐2 generally occur, but are repressed if a methyl group is on C‐1. Transfers from C‐5 to C‐2 can occur, but are less favorable than 1‐3 transfers. Endo‐2‐acetylnorbornanes undergo a γ‐hydrogen transfer from C‐5 with ring fission.
