Synthetic methodologies for C-C and C-N bond formation involving alkyl radicals

C-C and C-N bonds are some of the most common structures in molecules ranging from drugs to catalysts and to food additives. Many coupling reactions were developed to form these types of bonds with excellent selectivity and good performance. Still, the syn ...

Extrinsic Defects in Amorphous Oxides: Hydrogen, Carbon, and Nitrogen Impurities in Alumina

Alfredo Pasquarello, Francesco Ambrosio, Zhendong Guo

We present a procedure for addressing extrinsic defects in amorphous oxides, in which the most stable defect configurations are identified through ab initio molecular dynamics in various charge states and studied through hybrid functional calculations. The ...

Towards a frustrated Lewis pair-ionic liquid system

Paul Joseph Dyson, Rosario Scopelliti, Gabor Laurenczy, Zhaofu Fei, Felix Daniel Bobbink, Emilia Paunescu, Florian Gérald Abela

An ionic liquid encompassing a bulky tertiary amine was synthesized and used as a dual solvent-reactant for the formation of a frustrated Lewis pair with tris(pentafluorophenyl) borane, forming a pseudo-frustrated Lewis pair-ionic liquid system. The ionic ...

Reversible Dihydrogen Activation and Hydride Transfer by a Uranium Nitride Complex

Marinella Mazzanti, Farzaneh Fadaei Tirani, Marta Falcone, Lok Nga Poon

Abstract: Cleavage of dihydrogen is an important step in the industrial and enzymatic transformation of N2 into ammonia. The reversible cleavage of dihydrogen was achieved under mild conditions (room temperature and 1 atmosphere of H2) by the molecular ura ...

Suzuki-Miyaura cross-coupling of non-activated alkyl halides catalyzed by well-defined nickel pincer complexes

Thomas Clément Di Franco

Metal-catalyzed cross-coupling reactions are powerful and widespread methods for the carbon-carbon bond formation. Among the electrophile partners, non-activated alkyl halides remain challenging substrates because of their reluctance towards oxidative addi ...

Solvent-free synthesis and decomposition of Y(BH4)(3)

Philippe Mauron, Yan Yan

The direct and solvent-free synthesis of yttrium borohydride was achieved by reactive ball milling of yttrium hydride in diborane/hydrogen atmosphere. The product contains only the solid elemental hydride as remaining contaminant. Yields above 75% were obt ...

Impurity Gas Analysis of the Decomposition of Complex Hydrides

Andreas Züttel, Shunsuke Kato, Elsa Callini

This study aims at an investigation of the impurity gases emitted during the decomposition of borohydrides. For this we have set up a quantitative gas analysis based on a combination of FTIR spectroscopy and gravimetry. We show that the emission of various ...

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 ...

Ruthenium Catalysts for the Kharasch Reaction

Kay Severin

Recent advances in the development of ruthenium catalysts for the atom transfer radical addn. of polyhalogenated compds. to olefins ('Kharasch reaction') are described. Three classes of homogeneous catalysts are discussed: halfsandwich complexes with h6-ar ...

High resolution photoelectron spectra of carbon cluster anions and their monohydrides

Andreas Osterwalder

The smaller carbon cluster anions, Cn- (n = 2-11), and their monohydrides, CnH- have been studied previously using anion photoelectron spectroscopy. In many cases, vibrational structure is obsd., but much of the structure remains hidden due to the resoln. ...
