The splitting in the electrospray ionization mass spectrometer of several azulenes substituted in seven-membered ring with 2-thien-2-ylvinyl moiety was analyzed and some general features of fragmentation were evidenced. The fragmentation of propane substituted with azulenes and thienyl moieties was also discussed. Both classes of compounds are obtained in the condensation of alkylazulenes with thiophenealdehyde or the corresponding azomethyne.
