Description and Uses

3-Chloro-2,4,5,6-tetrafluoropyridine (3-chlorotetrafluoropyridine) is a fluoropyridine derivative. Its quantum mechanical calculations of energies, geometries and vibrational wave numbers have been performed by DFT level of theory. The interpretation of its FT-IR and FT-Raman spectra have been reported. It forms corresponding organo-zinc compound by reacting with zinc. 3-Chlorotetrafluoropyridine reacts with tris(diethylamino)phosphine (P(NEt)₃) in the presence of a proton donor to form product with fluorine replaced by hydrogen at position 4.
