Solvent-free synthesis of novel steroidal 2-aminopyridines

Steroids, 2016
The synthesis of novel steroidal 3-cyano-2-aminopyridines using enaminonitrile and various primary amines was established under solvent-free condition. Structures of the new compounds were characterized by MS, 1H and 13C NMR data and the structure of 2-aminopyridine of the product 5b was further confirmed by X-ray analysis.

Thermochemistry of 2-Aminopyridine (C5H6N2)(s)

Journal of Solution Chemistry, 2011
The molar enthalpies of solution of 2-aminopyridine at various molalities were measured at T = 298.15 K in double-distilled water by means of an isoperibol solution- reaction calorimeter. According to Pitzer's theory, the molar enthalpy of solution of the title compound at infinite dilution was calculated to besolH ∞ m = 14.34 kJ · mol −1 , and Pitzer ...

Bis(μ-2-aminopyridine)bis[(trifluoroacetato)silver(I)]

Acta Crystallographica Section C Crystal Structure Communications, 2004
The title compound, [Ag2(C2F3O2)2(C5H6N2)2], is a dinuclear AgI complex with inversion symmetry. Each Ag atom is three-coordinated by two N atoms from two different 2-aminopyridine ligands and by one O atom from a trifluoroacetate anion, giving an approximately trigonal coordination environment.

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
