Cuneane (from Latin cuneus 'wedge') is a saturated hydrocarbon with the formula C₈H₈ and a 3D structure resembling a wedge, hence the name. Cuneane may be produced from cubane by metal-ion-catalyzed σ-bond rearrangement. Similar reactions are known for homocubane (C₉H₁₀) and bishomocubane (C₁₀H₁₂).
