Propalene or bicyclo[1.1.0]buta-1,3-diene is a theoretical polycyclic hydrocarbon composed of two fused cyclopropene rings. Computational studies indicate that the molecule would be planar, with the carbon framework forming a parallelogram that has distinctly alternating short and long carbon–carbon bonds.
