Abstract: 

Hexaphenylethane is unstable, a phenomenon traditionally attributed to
steric repulsion between the six phenyl rings. However, adding 12 bulky tert‐butyl groups, one to each of the 12 meta
positions, gives a stabile ethane derivative (see space‐filling model
and potential energy curve for the dissociation of the central CC
bond). This unexpected stabilization is shown to result from attractive
dispersion interactions between the substituents.
