with amines via N-heterocycles assisted selective C-Fbondcleavage in the absence of transition metal catalysts. Studies had shown that the Li/F interaction significantly promoted the cross-coupling reaction. Unexpectedly, an amination of orthoC-Fbond on the pyridine ring was observed for 2-(2-fluorophenyl)-6-fluoropyridine, in which the C-Fbond on benzene ring was intact.
