Tetramethylcyclooctatetraene dication

A dication derived from 1,3,5,7-tetramethylcyclooctatetraene is formed at —78 C in SO2CI by reaction with SbFj. Both the proton and carbon NMR spectra indicate that the ion is a symmetrical, diamagnetic species, and the chemical shifts are consistent with an... [Pg.527]

If 1,3,5,7-tetramethylcyclooctatetraene is treated at low temperature (-78 °C) with SbF5/S02ClF (strongly oxidizing conditions) a dication is formed. This cation, unlike the neutral compound, is planar and all the C-C bond lengths are the same. [Pg.172]
