Microwave spectrum of 2-aminopyridine

Journal of Molecular Spectroscopy, 1972
The microwave spectra of 2-aminopyridine-NH2, -ND2, and of both of the two possible -NHD molecules have been observed and assigned in the 0+ vibrational state of the amino group inversion vibration; the assignment for three of the molecules in the 0− state is also made.

Selective formylation of 2-aminopyridines

Journal of the Chemical Society, Chemical Communications, 1974
The specific ortho-formylation of 2-aminopyridines has been accomplished via the rearrangement of azasulphonium salts derived from 2-aminopyridines and dithian, and through the effective oxidation of 2-amino-3-methylthiomethylpyridines.

Hydrogen bond energies of 2-aminopyridine dimer and 2-aminopyridine-2-pyridone complex formation

Spectrochimica Acta Part A: Molecular Spectroscopy, 1984
Abstract The formation energies of 2-aminopyridine dimer and 2-aminopyridine-2-pyridone complex were measured in C 6 D 6 solution by 1 H-NMR spectroscopy and values of 25.1 and 44.6 kJ/mol were obtained. The former value is about twice the magnitude of hydrogen bond energies which are generally observed for the N---HN system, and latter value is ...

General and Mild Preparation of 2-Aminopyridines

Organic Letters, 2010
A general and facile one-pot amination procedure for the synthesis of 2-aminopyridines from the corresponding pyridine-N-oxides is presented as a mild alternative to S(N)Ar chemistry. A variety of amines and heterocyclic-N-oxides participate effectively in this transformation which uses the phosphonium salt, PyBroP, as a means of substrate activation.
