rings with 7 or more members rings with 7 or more members Q 0050 -076Generation, Characterization and Some Reactions of 1,1-Ethylene-1H-azulenium Ion.-The title cation (VII), which is characterized as intermediate in solution by NMR, is stable up to -20 • C. At higher temperatures it seems to transform to ion (VIII). Attempts to trap the latter cation are unsuccessful. -(ODA, M.; KAJIOKA, T.; OKUJIMA, T.; ITOH, S.; MORITA, N.; MIYATAKE, R.; KURODA, S.; Chem.
