Abstract

The titled new non linear non benzenoid quinone compounds of cyclohepta [a] phenalene- 6, 10-,-6, 12-,-7, 10-, and-7, 12-diones have been synthesized. The dicationic species formed from quinones by protonation in a strong acid were revealed as diatropic compounds instead of a 16-pi electron system by an examination of spectral measurements, such as the 1 H NMR and UV spectra. The stability of these quinones, dicationic species, and dianonic ...
