Abstract The reactivity ratio between the three‐ and four‐membered cyclic ammonium ions in ring‐opening elimination reactions was measured. The comparison with the analogous ratio obtained in a previous study on ring‐opening substitution reactions suggests a substantial difference in the effect of the stereochemical factors governing the two ring‐opening reactions and confirms the anomalous behaviour of small rings in the ring‐opening substitution reaction.
