[摘要]：2-[1,3-Bis(ethoxycarbonyl)azulen-6-yl]ethynyltriphenylphosphonium bromide was prepared from diethyl 6-ethynyl-1,3-azulenedicarboxylate. Its NMR spectroscopic property was made clear. Furthermore, its reactivity with o-substituted aniline was studied, comparing with 1- and 2-ethynyl azulene derivatives. We found that 2-[3-(methoxycarbonyl)azulen-1-yl]ethynyltriphenylphosphonium bromide also reacted with o-substituted anilines in CHCl3 to give corresponding 2-[1,3-bis(ethoxycarbonyl)azulen-6-yl]benzoazoles. However, in DMSO another products were obtained. |
