Constantly in motion : The attack of the tert ‐butyl cation on benzene gives a π complex whose stability is similar to that of the σ complex. The frequently employed notation for real or proposed π complexes (see picture) has now to be interpreted as indicating the mobility of the cation along the ring periphery: the position of the cation above the delocalized π‐electron belt cannot be established.
