Basicity of some amines in acetonitrile was written by Peips, M.;Koppel, U.;Pihl, V.;Koppel, I.. And the article was included in Reaktsionnaya Sposobnost Organicheskikh Soedinenii in 1976.Application of 7528-78-1 This article mentions the following:
The pKBH+ values of several amines in MeCN were linearly correlated with the Taft σ* constants when a factor taking into account the primary, secondary, or tertiary nature of the amine was used. Although the pKBH+ values in MeCN and in H2O differed by 5-8 orders of magnitude, the amines exhibited comparable sensitivity to structural effects in these solvents. In the experiment, the researchers used many compounds, for example, 3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1Application of 7528-78-1).
3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1) belongs to nitriles. The electronic structure of nitriles is very similar to that of an alkyne with the main difference being the presence of a set of lone pair electrons on the nitrogen. Nitrile groups in organic compounds can undergo a variety of reactions depending on the reactants or conditions. A nitrile group can be hydrolyzed, reduced, or ejected from a molecule as a cyanide ion.Application of 7528-78-1
