Rotational disorder in lithium borohydride

LiBH4 has been discussed as a promising hydrogen storage material and as a solid-state electrolyte in lithiumion batteries. It contains 18.5 wt% hydrogen and undergoes a structural phase transition at 381K which is associated with a large increase in rotat ...

Synthesis of Triazenes with Nitrous Oxide

Paul Joseph Dyson, Rosario Scopelliti, Kay Severin, Tina Riedel, Gregor Kiefer

Triazenes are valuable compounds in organic chemistry and numerous applications have been reported. Furthermore, triazenes have been investigated extensively as potential antitumor drugs. Here, we describe a new method for the synthesis of triazenes. The p ...

Chemoselective Hydrogenation and Transfer Hydrogenation of Aldehydes Catalyzed by Iron(II) PONOP Pincer Complexes

Rosario Scopelliti, Xile Hu, Simona Mazza

Iron-catalyzed hydrogenation has drawn much attention, yet the scope and chemoselectivity of iron catalysis warrant further improvement. Here we report new iron pincer complexes as chemoselective hydrogenation and transfer hydrogenation catalysts. Several ...

Base-Catalyzed Intramolecular Hydroamination of Cyclohexa-2,5-dienes: Insights into the Mechanism through DFT Calculations and Application to the Total Synthesis of epi-Elwesine

Kurt Schenk

The base-catalyzed intramolecular hydroamination of 1-ethylaminocyclohexa-2,5-dienes is described. The transformation proceeds through isomerization of the cyclohexa-1,4-dienyl fragment into the corresponding conjugated 1,3-diene prior to the hydroaminatio ...

Reactivity enhancement of oxide skins in reversible Ti-doped NaAlH4

The reversibility of hydrogen sorption in complex hydrides has only been shown unambiguously for NaAlH4 doped with transition metal compounds. Despite a multitude of investigations of the effect of the added catalyst on the hydrogen sorption kinetics of Na ...

Atmospheric amines and ammonia measured with a chemical ionization mass spectrometer (CIMS)

Athanasios Nenes, Satoshi Takahama, Giulia Ruggeri, Hairun Guo

We report measurements of ambient amines and ammonia with a fast response chemical ionization mass spectrometer (CIMS) in a southeastern US forest and a moderately polluted midwestern site during the summer. At the forest site, mostly C3-amines (from pptv ...

Insight into the decomposition pathway of the complex hydride Al3Li4(BH4)(13)

Elsa Callini

The decomposition pathway of the complex hydride Al3Li 4(BH4)13 is in the focus of this study. Initially the compound attracted great interest due to its high H2 capacity (17.2 wt.%) and desorption at moderate temperatures (<100 °C). This work sheds lig ...

Hydrogen trapping in delta-Pu: insights from electronic structure calculations

Michael Frederick Francis

Density functional theory calculations have been performed to provide details of the structural and charge-transfer details related to the solid solution of hydrogen in (delta)-plutonium. We follow the Flanagan model that outlines the process by which hydr ...
