## Abstract Mass spectrometrical and ^1^H‐NMR.‐analyses of the __exo__‐5‐norbornen‐2‐yl acetate, formed by acetolysis of __endo__‐5‐norbornen‐2‐yl‐2‐__exo__‐d brosylate, demonstrate that the deuterium initially on C(2) migrates partially (30%) onto C(1) (mechanism Ia or Ib). No deuterium could be d
