General description
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.

Quantum mechanical calculations of energies, geometries and vibrational wave numbers of 3-chloro-2,4,5,6-tetrafluoropyridine and 4-bromo-2,3,5,6-tetrafluoropyridine have been performed by DFT level of theory using B3LYP/6-31+G(d) and B3LYP/6-311++G(d,p) as basis sets. The optimized geometrical parameters obtained by B3LYP method show good agreement
