Functionalized Oxatriquinanes and Their Structural Equilibrium in Protic Solvent

Chemical and Pharmaceutical Bulletin, 2014
We synthesized oxatriquinane hexafluorophosphate bearing an ethoxycarbonylmethyl group 7 or a 2-oxopropyl group 11. Both of these organic oxonium cation compounds were obtained as stable solids. However, (1)H-NMR analysis showed that oxatriquinane 7 was present as the oxonium cation in aprotic solvent CD₃CN, but was in rapid equilibrium with ring ...

Nucleofugality and Nucleophilicity of Fluoride in Protic Solvents

The Journal of Organic Chemistry, 2012
A series of p-substituted benzhydryl fluorides (diarylfluoromethanes) were prepared and subjected to solvolysis reactions, which were followed conductometrically. The observed first-order rate constants k(1)(25 °C) were found to follow the correlation equation log k(1)(25 °C) = s(f)(N(f) + E(f)), which allowed us to determine the nucleofuge-specific ...

Proton solvation in protic and aprotic solvents

Journal of Computational Chemistry, 2016
Protonation pattern strongly affects the properties of molecular systems. To determine protonation equilibria, proton solvation free energy, which is a central quantity in solution chemistry, needs to be known. In this study, proton affinities (PAs), electrostatic energies of solvation, and pKA values were computed in protic and aprotic solvents.

The fate of phosphobetaines in protic solvents

Journal of the Chemical Society D: Chemical Communications, 1971
Reactions in protic solvents of 2-hydroxyalkyltriphenylphosphonium salts with base and of triphenylphosphine with propylene oxide produce numerous unexpected products, thereby revealing a much wider scope of reactivity for the phosphobetaine intermediates of these reactions than was previously recognized.

Anion solvation in protic solvents

Journal of the Chemical Society, Chemical Communications, 1977
Spectroscopic evidence is advanced in favour of the concept of continuous hydrogen-bonding from anions into bulk solvent with no intervention of an intermediate structureless region.
