The reactivity of 4-, 8- and/or 6-azulene methyl group in condensation with thiophene-2-carboxaldehyde or the corresponding azomethines in basic media was studied. The compounds obtained and the yields depend on the starting materials as well as on the base used. esides mono- and di(2-(thien-2-yl)vinyl)azulenes, many carbonyl derivatives and other more complicated compounds were obtained and characterized. Amounts of oligomers and polymers are also formed, with unassigned structures. Starting from di- or trimethyl-substituted azulenes, more that one methyl group can be involved in the condensation.
