 note = {3-(3-methoxycarbonylazulen-1-yl)ethynyltriphenylphosphonium bromide was prepared from methyl 3-formylazulenecarboxylate. Its resonance structures were discussed on the basis of the H-1 and C-13 NMR spectroscopy. Furthermore, its reactivity with o-substituted aniline was examined. We found that 2-(1-methoxycarbonyl-azulen-3-yl)ethynyltriphenylphosphonium bromide reacted with o-substituted aniline except 2-aminophenol to give corresponding methyl 3-(benzazol-2-yl)azulene-1-carboxylate., Article, Heterocycles.
