Compound 94 and the vinylogue of trithione (95)are not likely to prove particularly stable. Just as in the unisolable cyclopentadienone, the electronegativity of the exocyclic (94) (95) (96) atom opposes the tendency of the rings in compounds 94 and 95 to complete a x-electron sextet or decet.

This view is supported by a study of ESR, electronic, and near-infrared spectra. ESR spectra of 2,l-dimethyl- and 2,l-dichlorothianthrene radical cations have also been studied.
