“Does Water Affect the Acidity of Surfaces? The Proton-Donating Ability of Silanol and Carboxylic Acid Groups at Mesoporous Silica.”

Solvation at the interphase:

A study of the influence of water on the effective acidity of silanol and carboxylic acid groups of propionic acid functionalized SBA-15 reveals that to affect the proton-donating ability of an acidic group at the surface, water should be able to form a solvation shell around that group. As a result, water does not affect the acidity of native SBA-15 but dramatically enhances that of SBA-15 functionalized with propionic acid moieties.

“Difference between ¹H NMR signals of primary amide protons as a simple spectral index of the amide intramolecular hydrogen bond strength.”

J. Phys. Org. Chem. 2011, 25 (4), 287-295.
DOI: 10.1002/poc.1910

Abstract

The effect of the intramolecular H-bonding of the primary amide group on the spectral properties and reactivity of this group towards electrophiles has been studied in systematic rows of 1,2,5,6,7,8-hexahydro-7,7-dimethyl-2,5-dioxo-1-R-quinoline-3-carboxamides and 2-aryliminocoumarin-3-carboxamides using ¹H and ¹⁵N NMR spectroscopy and the kinetics of model reactions.
