✦ Synopsis

In tie presence of boron tritluoride, pertluomaJky!itJdums generated in situ from the nzaction of n-pertlwnvaJky1 iodides witb metJzylJitJdum-JitJdum bmmide smoothly added to a carbon-nitrogen double bond of bicyclic azaare nes and dia.&es lo give tie cormspondingpertluomaJ&J&d o%ydm betemcycJes, wJdcJl o&n underwent sponlaneous aromatization in air. PerJluomaJkyJation occurred prefemntJaJJy at the car&m next to nhogen in azaarenes even when the carbon atom ~85 occupied by an aJkyJ substitoent. only one exception observed was he

reaction of ecnLfine where a pert7uomaJkyJ gmop was intrcduced at 9 posidon.
