説明
π-Electronic structures of 5H,11H+-cyclohepta[b]quinoxalinium ions and their O- and S-analogues were elucidated by means of 1H and 13C NMR spectra, electronic spectra, and theoretical calculations. Consequently, it was shown that these compounds had very stable aromatic characters with positive resonance energies and that the 6π-tropylium-6π-benzonoid form plays an important role for the π-conjugation structure.
