The spontaneous rearrangement of allylic azides is thought to be a sigmatropicreaction. Presented herein is a detailed investigation into the rearrangement of several allylic azides. A combination of experiments including equilibrium studies, kinetic analysis, density functional theory calculations, and selective 15N-isotopic labeling are included. We conclude that the Winstein rearrangement occurs
