[1.1.1]Propellane is a highly strained smallest tricyclic hydrocarbon, and its reactivity is primarily focused on addition reactions across the strained C-C bond, leading to the formation of bicyclo[1.1.1]pentane derivatives. Herein, the authors present a [2,3]-sigmatropic rearrangement that uses [1.1.1]propellane as a carbene precursor to rapidly access allenylated or allylated methylenecyclobutanes.
