Synthesis of Room-Temperature Ionic Liquids with the Weakly Coordinating [Al(ORF)4]- Anion (RF=C(H)(CF3)2) and the Determination of Their Principal Physical Properties

Paul Joseph Dyson, Gabor Laurenczy, Safak Bulut

A large series of ionic liqs. (ILs) based on the weakly coordinating alkoxyaluminate [Al(hfip)4]- (hfip: hexafluoroisopropoxy) with classical as well as functionalized cations were prepd., and their principal phys. properties detd. M.ps. are between 0 ([C4 ...

Local Effects in the X-ray Absorption Spectrum of Salt Water

Nicola Marzari, Giulia Galli Gygi

Both first-principles molecular dynamics and theoretical X-ray absorption spectroscopy have been used to investigate the aqueous solvation of cations in 0.5 M MgCl(2), CaCl(2), and NaCl solutions. We focus here on the species-specific effects that Mg(2+), ...

Parahydrogen-induced polarization in alkyne hydrogenation catalyzed by Pd nanoparticles embedded in a supported ionic liquid phase

Lioubov Kiwi

Parahydrogen-induced polarization was observed in the gas phase heterogeneous hydrogenation of propyne catalyzed by Pd-0 nanoparticles embedded in an ionic liquid phase supported on activated carbon fibers (Pd-0/SILP/ACF). The results were markedly differe ...

Three-Phase Catalytic Hydrogenation of a Functionalized Alkyne: Mass Transfer and Kinetic Studies with in Situ Hydrogen Monitoring

Albert Renken, Lioubov Kiwi, Martin Grasemann

Systematic studies of mass transfer interactions with intrinsic reaction kinetics were performed for the threephase selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) over a modified Pd/CaC

Heterogeneous dehalogenation of arylhalides in the presence of ionic liquids

Gabor Laurenczy

Dehydrohalogenation of haloaromatics in ionic liquids derived from ethylmethylimidazolium or similar salts has been performed using Pd-C, Pd(OAc)2 and other catalysts using formate salts as a hydrogen source. In the ionic liquid [emim][BF4< ...

Proton dynamics in superprotonic CsHSO(4)

Nicola Marzari

We present a detailed study of proton dynamics in the hydrogen-bonded superprotonic conductor CsHSO(4) from first-principles molecular dynamics simulations, isolating the subtle interplay between the dynamics of the O-H chemical bonds, the O center dot cen ...

How to predict the physical properties of ionic liquids: a volume-based approach

Paul Joseph Dyson, Corinne Daguenet

The mol. vol. Vm (i.e., the sum of the ionic vols. Vion of the constituent ions) of an ionic liq. (IL) in combination with an anion-dependent empirical relationship is all one needs to predict phys. properties such as viscosity, cond., and d. of [N(CN)2]-, ...

Catalytic hydrogenation of alkenes under biphasic conditions

Corinne Daguenet

Ruthenium(II)-arene diphosphine complexes are shown to be effective precursors for the catalytic hydrogenation of the C=C bond in an aqueous biphase using molecular hydrogen as the hydrogen source. A mechanistic study performed in water, utilizing high gas ...
