Mechanistic Studies Related to Nickel-Catalyzed Alkyl-Alkyl Cross Coupling Reactions

Jan Breitenfeld

Cross-coupling reactions of non-activated alkyl halides are potentially useful chemical transformations. At the same time, however, they are challenging due to a series of unproductive side reactions. Recently, significant progress has been made to overcom ...

A Caveat on SCC-DFTB and Non-covalent Interactions Involving Sulfur Atoms

Riccardo Petraglia

Accurate modeling of non-covalent interactions involving sulfur today is ubiquitous, particularly with regards to the role played by sulfur-containing heterocycles in the field of organic electronics. The density functional tight binding (DFTB) method offe ...

Hydrogen Sorption in Li12C60

Philippe Mauron

The lithium-intercalated fulleride Li12C60 was investigated in view of a lightweight hydrogen storage material due to the low molecular weight of its constituents. Deuterium (D2) absorption in Li12C60 shows an uptake of up to 9.5 mass % D2 (equivalent to ∼ ...

Mail-Order Metal–Organic Frameworks (MOFs): Designing Isoreticular MOF-5 Analogues Comprising Commercially Available Organic Molecules

Berend Smit

Metal-organic frameworks (MOFs), a class of porous materials, are of particular interest in gas storage and separation applications due largely to their high internal surface areas and tunable structures. MOF-5 is perhaps the archetypal MOF; in particular, ...

Synthesis, Reactivity, and Catalytic Application of a Nickel Pincer Hydride Complex

Rosario Scopelliti, Xile Hu, Jan Breitenfeld

The nickel(II) hydride complex [(MeN2N)Ni-H] (2) was synthesized by the reaction of [(MeN2N)Ni-OMe] (6) with Ph2SiH2 and was characterized by NMR and IR spectroscopy as well as X-ray crystallography. 2 was unstable in solution, and it decomposed via two re ...

Surface and bulk reactions in borohydrides and amides

Shunsuke Kato, Elsa Callini

Complex hydrides such as LiBH4 and LiNH2 exceed the gravimetric hydrogen density of transition metal hydrides by one order of magnitude. However, hydrogen in complex hydrides is covalently bound and arranged in subunits e.g. [NH2]- and [BH4] - with a fixed ...

CO2 hydrogenation on a metal hydride surface

Davide Ferri, Shunsuke Kato

The catalytic hydrogenation of CO 2 at the surface of a metal hydride and the corresponding surface segregation were investigated. The surface processes on Mg 2NiH 4 were analyzed by in situ X-ray photoelectron spectroscopy (XPS) combined with thermal deso ...

Interface reactions and stability of a hydride composite (NaBH4 + MgH2)

Shunsuke Kato

The use of the interaction of two hydrides is a well-known concept used to increase the hydrogen equilibrium pressure of composite mixtures in comparison to that of pure systems. The thermodynamics and reaction kinetics of such hydride composites are revie ...

Soudure par interdiffusion dans les systèmes Au-In et In-Ni

Léa Deillon

Hermiticity is an essential requirement of a MEMS package for a device to work properly. Hermeticity also must be preserved during the operations following packaging, during which the package bond should not remelt. Bonding temperature is limited however t ...

Synthesis Mechanism of Alkali Borohydrides by Heterolytic Diborane Splitting

Similar to alane in alanates, borane species are assumed to be the mass transport intermediate in the hydrogen storage reaction MH + B + 3/2H2 MBH4 with M = Li and Na. One possible substep of this reaction is the interaction of diborane with the alkali hyd ...
