EFFECT OF SUBSTITUENTS ON CHEMICAL SHIFT OF PROTONS OF THE AMINO GROUP IN PMR SPECTRA OF SUBSTITUTED AMINOPYRIDINES

Article abstract of DOI:10.1007/BF00506847

The effect of substituents on the chemical shift of the protons of the amino group in six series of m- and p-substituted 2-, 3- and 4-aminopyridines (in DMSO) was studied by correlation analysis using the inductive and resonance constants.The peculiarities of the pyridine ring in the transmission of the electronic effects of the substituents are discussed.
