Synthesis of azulenylheterocyclic compounds using 2-(2-azulenyl)ethynyltriphenyl-phosphonium bromide

摘要

2-(2-Azulenyl)ethynyltriphenylphosphonium bromide was prepared from 2-formylazulene.Its NMR spectroscopic property was made clear.Furthermore,its reactivity with o-substituted aniline was examined.We found that 2-(2-azulenyl)ethynyltriphenylphosphonium bromide reacted with o-substituted aniline to give corresponding 2-(2-azulenyl)benzoazoles.
