چکیده

Does an OH-flipping barrier hinder H-bond formation between a gas phase molecule and a water monolayer whose free OH ligands point toward a substrate? According to density functional theory calculations for water on Pt(111) the answer is yes, when the molecule is CO or N2, but no when it is NH3. The difference is the relatively strong attraction of the NH3 lone pair to free OH ligands.

Synthesis of electron-poor N-Vinylimidazole derivatives catalyzed by Silica nanoparticles under solvent-free conditions

Protonation of the highly reactive 1:1 intermediates, produced in the reaction between triphenylphosphine and acetylenic esters, by NH-acids such as azathioprine, imidazole or theophylline leads to the formation of vinyltriphenylphosphonium salts, which undergo a Michael addition reaction with a conjugate base to produce phosphorus ylides. Silica nanoparticles (silica NPs were prepared by therm...

A low barrier in the reaction pathway between the double Rydberg isomer of OH(3) (-) and a hydride-water complex indicates that the former species is more difficult to isolate and characterize through anion photoelectron spectroscopy than the well known double Rydberg anion (DRA), tetrahedral NH(4) (-).
