The title compounds (indolo[2,3-b][1]azaazulenes) were synthesized from 2-hydrazino-1-azaazulene and cyclohexanone utilizing Fischer’s indole synthesis, followed by dehydrogenation of the N-acetylated tetrahydro precursor with DDQ. Structures of the neutral and cationic species of these compounds were discussed on the basis of the spectral data.
