Shkurko, O. P. et al. published their research in Zhurnal Organicheskoi Khimii in 1981 | CAS: 1753-48-6

2-Aminopyrimidine-5-carbonitrile (cas: 1753-48-6) belongs to nitriles. Nitrile compounds can be prepared by the incorporation of a cyanide source through C–C bond formation or by dehydration of primary carboxamides. Asymmetric bioreduction of nitriles is an attractive route to produce optically active nitriles as current metal-catalyzed hydrogenations tend to have low reactivity.Category: nitriles-buliding-blocks

Equilibrium NH-acidity of substituted aminopyrimidines was written by Shkurko, O. P.;Terekhova, M. I.;Petrov, E. S.;Mamaev, V. P.;Shatenshtein, A. I.. And the article was included in Zhurnal Organicheskoi Khimii in 1981.Category: nitriles-buliding-blocks This article mentions the following:

The transmetalation method was used to determine the NH acidity (pK) of thirty-nine 2-, 4-, and 5-aminopyrimidines; the pK values ranged from 17.7 for 5-nitro-2-pyrimidinamine to 30.2 for 2-(dimethylamino)-5-pyrimidinamine. Comparison with the pK of aniline showed that the ring N atoms had an acidifying effect in the order 4-aza ≫ 2-aza > 3-aza. LFER of the pK vs. NMR chem. shifts, and inductive or resonance substituent constants were described. In the experiment, the researchers used many compounds, for example, 2-Aminopyrimidine-5-carbonitrile (cas: 1753-48-6Category: nitriles-buliding-blocks).
