Dibenzoselenophene anion-radical

Dibenzoselenophene anion-radical (190) is the only radical of this class whose ESR spectrum has been analyzed. Two groups found essentially the same proton hyperfine splittings. Those indicated in gauss in 190 were given by Chiu and Gilbert who also measured the Se splitting their spectrum was obtained by reduction of the heterocycle with potassium in DME. A low temperature ( — 50°C) was necessary in order to obtain...
