## Abstract The title compound 5 was obtained from 2,2β€²,3,3′‐tetramethylbiphenyl in a multi‐step reaction sequence leading to the bis(propellane). X‐ray structure analysis proved the identity of bis(propellane). In the solid state the molecule possesses roughly a twofold symmetry axis perpendicular
