consecutive treatment of 2,6-difluoropyridine with lithium diisopropylamide and N,N-dimethylformamide. Regioselective displacements of fluorine from the aldehyde by nucleophiles were carried out. To demonstrate the versatility of the organometallic approach, some two dozens of further 2,6-difluoropyridine derivs. were prepd. applying a combination of modern organometallic methods such as site selective
