Popis:	1,1-Dimethylcycloprop[e]azulene and 1,1-dimethylcycloprop[f]azulene derivatives were prepared through a short synthesis from thiophene-1,1-dioxides using a Houk-Leaver azulene synthesis. The strain caused by the fusion of the cyclopropane ring had no effect on electrophilic aromatic substitution reactions. X-ray structures of these compounds showed that cycloprop[e]azulenes have no or very small strain induced bond localisation, whereas cycloprop[f]azulene shows some minor localisation.
