Electrophilic benzylation of 2‐aminopyridine ring

Journal of Heterocyclic Chemistry, 1991
AbstractIn the reaction of 2‐aminopyridine and its 3‐ or 5‐methyl derivatives with benzyl chloride used in a molar ratio of 1:2, benzylation of 2‐aminopyridine ring has been stated that 2‐amino‐3‐ or 5‐benzylpyridines c as the major products were obtained.

Reactions of 2‐aminopyridine with picryl halides

Journal of Heterocyclic Chemistry, 1976
Abstract2‐Aminopyridine reacts with picryl halides to give mixtures of 1‐picryl‐2‐(N‐picrylimino)‐1,2‐dihydropyridine and 2‐(N‐picrylamino)pyridine. When picryl fluoride is treated with an excess of 2‐aminopyridine, the 1‐picryl‐2‐(N‐picrylimino)‐1,2‐dihydropyridine reacts further with 2‐aminopyridine to yield two molecules of 2‐(N‐picrylamino)pyridine

Carbonylation of 2-aminopyridine with carbon monoxide

Chemistry of Heterocyclic Compounds, 1971
α-Aminopyridine is smoothly carbonylated by carbon monoxide under pressure to give a-formamidopyridine. Phenothiazine and acridone are not carbonylated under these conditions.

Luminescence of hydrogen-bonded 2-aminopyridine dimers

Journal of Molecular Structure, 1988
Abstract Fluorescence of 2-aminopyridine (2AP) in nonpolar solvents undergoes drastic changes upon lowering of temperature: a red shift of the emission occurs with a simultaneous intensity decrease. This behaviour is interpreted as being due to the formation of 2AP dimers. No spectral changes with temperature are observed when 2AP is immobilized in a
