The Payne rearrangement is an anionic process in which nucleophilic substitution causes equilibration between to ethylene oxide systems. A combination of product ion, labelling (2H and 18O) and computational studies, shows that the Payne rearrangement (shown below) competes with formation of an oxetane ring system in the gas phase.

Corresponding processes occurring for oxetan and tetrahydrofuran analogues of the Payne rearrangement will be described.
