Sequential lithiations of 1-benzylimidazole, 1, and of 1-benzyl-1,2,4-triazole,2, followed by treatment with electrophiles others than alkyl halides result in reactions at C-2.However, benzyl halides and, to a certain extent, iodomethane react at the N-benzyl carbon atom.An explanatory hypothesis based on steric ortho effects is advanced.
