title: Thermal [1,3] carbon sigmatropic rearrangements of vinylcyclobutanes.
abstract: Stereochemical, kinetic, and theory-based studies of the [1,3] carbon sigmatropic rearrangements of bicyclo[2.1.1]hex-2-enes, bicyclo[3.2.0]hept-2-enes, and monocyclic vinylcyclobutanes support the judgment that such reactions involve transient diradical structures traversing relatively flat potential energy surfaces.
