Electrochemical oxidations of thioethers: Modulation of oxidation potential using a hydrogen bonding network

Electrochemistry Communications, 2019
A highly efficient chemo-selective electrochemical oxidation of thioethers to sulfoxides and sulfones was developed. The hydrogen bonding network generated from hexafluoro-2-propanol (HFIP) and acetic acid (AcOH) plays an important role in the modulation

A model for the hydrogen bond [PDF]

Proceedings of the National Academy of Sciences, 1975
A model of the linear hydrogen bond has been devised which is characterized by three physical parameters of the isolated electron donor and proton donor molecules: μ A-H , the bond dipole moment; Δ I , the difference in ionization potential between that of the electron donor and the ...

“Hydridic Hydrogen-Bond Donors” Are Not Hydrogen-Bond Donors [PDF]

Journal of the American Chemical Society
Herein, we dismiss a recent proposal by Civiš, Hobza, and co-workers to modify the IUPAC definition of hydrogen bonds in order to expand the scope from protonic Y-Hδ+ to hydridic Y-Hδ- hydrogen-bond donor fragments [J. Am. Chem. Soc. 2023, 145, 8550].

Two isostructural carbamates: the o-tolyl N-(pyridin-3-yl)carbamate and 2-bromophenyl N-(pyridin-3-yl)carbamate monohydrates

Acta Crystallographica Section E: Crystallographic Communications, 2015
The title carbamate monohydrates, C13H12N2O2·H2O and C12H9BrN2O2·H2O, form isomorphous crystals that are isostructural in their primary hydrogen-bonding modes.

Hydrogen-Bonding-Mediated Selective Hydrogenation of Aromatic Ketones over Pd/C in Ionic Liquids at Room Temperature

, 2021
Selective hydrogenation of aromatic ketones without hydrogenation of aromatic rings over Pd/C is very interesting but still challenging. Herein, we report a hydrogen-bonding-mediated strategy for selective hydrogenation of aryl ketones to either aryl ...
