temperatures. An ionic mechanism triggered by the halide ion dissociation is proposed for the thermalrearrangement on the basis of a study using deuteriated imine 15m, and the effects of additives and solvents. On the other hand, difluorocyclopropyl imine undergoes a homolytic cleavage of cyclopropane 1,3-bond with lower activation energy than the dichlorocyclopropyl imine, and afforded the N-alkyl-3-fluoropyrrole
