Ueno, Tetsuya published the artcileSynthesis and properties of fluoroazulenes. II. Electrophilic fluorination of azulenes with N-fluoro reagents, Name: 1-Fluoropyridiniumtriflate, the publication is Bulletin of the Chemical Society of Japan (1996), 69(6), 1645-1656, database is CAplus.

1-Fluoro- and 1,3-difluoroazulenes were synthesized for the first time by the electrophilic fluorination of azulenes with N-fluoro reagents. Selective preparation of 1-fluoroazulenes were performed by the fluorination of Me azulene-1-carboxylates, followed by demethoxycarbonylation in 100% H3PO4. 2-Substituted azulenes were fluorinated in higher yields. In the 1H NMR of 1-fluoroazulene, long-range JFH values were not observed at H-2 and H-8, in contrast to those for 1-fluoronaphthalene. The 1-fluorine atom causes significant bathochromic shifts in the visible absorption of azulene, due to the so-called +Iπ effect.
