Abstract:
The (ammonio)amidyl (AA) groups, with the general structure of R3N+N--, represent a new class of π-electron-donating groups for the benzene-based π-conjugated molecules. This study investigated AA-substituted p-nitrobenzenes to assess the effects of acyclic, monocyclic, and bicyclic ammonium structures in the AA groups on the π-electron-donating ability and thermal stability of the structure. Quantum chemical calculations were performed that supported the experimentally observed favorable properties of the (quinuclidinio)amidyl (QA) group.

Basicity of Aliphatic Amines
To measure the basicity of amines, two conventions are generally used. The first defines Kb as the basicity constant for the deprotonation reaction of water by the amine, as presented in Figure 1. Conventionally, lower Kb indicates...

Acidity of 1-Alkynes
The acidic strength of hydrocarbons follows the order: Alkynes > Alkenes > Alkanes. The strength of an acid is commonly expressed in units of pKa — the lower the pKa, the stronger the acid. Among the hydrocarbons, terminal alkynes have lower pKa values and are, therefore, more acidic. For example, the pKa values for ethane, ethene, and acetylene are 51, 44, and 25, respectively, as shown here.
