TL;DR: In this paper, the formation of the [OH…O]+ hydrogen-bonded bridges of proton-Noxide systems in acetonitrile (a polar aprotic protophobic solvent) was studied using the potentiometric titration method.

TL;DR: In this article, a comparison of the cationic heteroconjugation constants in nitrobenzene with those measured in other non-aqueous solvents was made.

TL;DR: In this article, Cationic standard homoconjugation constants were determined in systems containing heterocyclic and aliphatic amine N -oxides, and pyridine, in two polar aprotic solvents: weakly basic protophobic nitromethane (NM); and strongly basic protophilic N, N -dimethylformamide (DMF).

TL;DR: In this article, an attempt has been made to determine potentiometrically standard acidityKao (BH + ) constants of protonated substituted pyridine N-oxides and cationic standard homoconjugation constantsKfo (BHB + ) of these acids conjugated with the Noxides in a binary solvent system.

TL;DR: In this article, the acidity constant values of protonated N-oxides in polar nonaqueous solvents were determined, and it was found that the cationic homo-and heteroconjugation constant values increased with decreasing solvent basicity and with increasing basicity of the N-oxide.
