Notes: [Auszug] Both oxygen atoms in the resultant peroxide thus originate in the hydrogen peroxide molecule. This must necessarily be the case in reaction (3), but it is also thought to apply in reactions of types (1) and (2). The reaction may proceed by either of the two established mechanisms of nucleophilic ...

Notes: 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 C11.
