Surprising acidity of hydrated lithium cations in organic solvents.
Lithium cations are shown to have a significant role in catalyzing oxygen and proton reduction along with S(N)1 reactions in biphasic systems. We propose that this catalytic effect is due to the surprising acidity of the hydrated cations; interactions between the cation and its surrounding solvation shell will make the constituent water molecules more acidic.
متن کاملUnfolding of Hydrated Alkyl Diammonium Cations Revealed by Cryogenic Ion Mobility-Mass Spectrometry.
Hydration of the ammonium ion plays a key role in determining the biomolecular structure as well as local structure of water in aqueous environments. Experimental data obtained by cryogenic ion mobility-mass spectrometry (cryo-IM-MS) show that dehydration of alkyl diammonium cations induces a distinct unfolding transition at a critical number of water molecules, n = 21 to 23, n = 24 to 26, and ...
متن کاملHydrated Disease
readable form a clear history of the conditions produced by the echinococcus in the various organs of the body. The memoir which prefaces the volume shews that Dr. John Daviea Thomas was a constant and diligent worker, and a man of whom the profession of medicine have cause to be proud. His special opportunities for studying hydatid disease render this work perhaps the most valuable on the subj...
متن کاملA conceptual framework chemistry of Hydrated Cations: Part I. Preliminary Ab Initio and QTAIM calculations on [Li(H20)nr (n=1,2,3).
Ion molecules with general chemical formula as [Li(H2O)] (n=1,2,3), have been chosen as model species toinvestigate the chemical properties of hydrated lithium cations. The RHF(SCVS)/UGBS level of calculationhas been used for obtaining equilibrium geometries and Rho(r) functions (electron density distributions). By theaid of fundamental physical theorems implemented in Quantum Theory of Atoms i...
