In the presence of boron trifluoride, perfluoroalkyllithiums generated in situ from tbe reaction of n-perfluoroalkyl iodides with methyllithium-lithium bromide smoothly added to a carbon-nitrogen double bond of bicyclic azaarenes and diazines to give the corresponding perfluoroalkylated dihydro heterocycles, which often underwent spontaneous aromatization in air. Perfluoroalkylation occurred preferentially
