The Arrhenius parameters for the unimolecular lactonisation of the K‐salts of the ω‐brom‐undecanoic and ω‐brom‐pentadecanoic acids have been determined. It has been shown that the reaction rate depends on the ionisation of the bromine, not on the cyclisation process. The observations have been discussed and, in particular, an explanation in kinetic terms is provided for the minimum yield of cyclic products near C 11 .
