## Abstract The title compound 5 was obtained from 2,2′,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
## Abstract The crystal structures of __N__‐aryl‐1,2,3,4‐tetrahydro‐3,3‐dimethyl‐2,4‐quinolinediones bearing methoxy‐ (**1**), methyl‐ (**2**), and chloro‐ (**3**) substituents in 2′‐position of the phenyl ring have been determined by X‐ray crystal structure analysis. The heterocyclic ring in **1–3
