A 1,3,2-Diazaphospholene-Catalyzed Reductive Claisen Rearrangement

Nicolai Cramer, Pavel Alexandrovich Donets, John Henry Reed, Solène Florie Miaskiewicz

1,3,2-Diazaphospholenes (DAPs) are an emerging class of organic hydrides. In this work, we exploited them as efficient catalysts for very mild reductive Claisen rearrangements. The method is tolerant towards a wide variety of functional groups and operates ...

CO2 and CO/H-2 Conversion to Methoxide by a Uranium(IV) Hydride

Rosario Scopelliti, Marinella Mazzanti, Marta Falcone

Here we show that a scaffold combining siloxide ligands and a bridging oxide allows the synthesis and characterization of the stable dinuclear uranium(IV) hydride complex [K-2{U(OSi((OBu)-Bu-t)(3))(3)(mu-O)(mu-H)(2)}], 2, which displays high reductive ...

Stabilization of volatile Ti(BH4)(3) by nano-confinement in a metal-organic framework

Andreas Züttel, Elsa Callini

Liquid complex hydrides are a new class of hydrogen storage materials with several advantages over solid hydrides, e.g. they are flexible in shape, they are a flowing fluid and their convective properties facilitate heat transport. The physical and chemica ...

Complex and liquid hydrides for energy storage

Andreas Züttel, Elsa Callini, Ping Chen

The research on complex hydrides for hydrogen storage was initiated by the discovery of Ti as a hydrogen sorption catalyst in NaAlH4 by Boris Bogdanovic in 1996. A large number of new complex hydride materials in various forms and combinations have been sy ...

Decamethylruthenocene Hydride and Hydrogen Formation at Liquid|Liquid Interfaces

Hubert Girault, Pekka Eero Peljo, Manuel Alejandro Méndez Agudelo, Thomas James Stockmann, Micheal Diarmaid Scanlon, Lucie Josette Renée Rivier

The formation and the dissociation of metal hydrides are key steps within the hydrogen evolution reaction (HER) pathway for photochemical water splitting, but also impacts a wide range of other catalytic, industrial, and biochemical reactions. Herein, we d ...

From oxide surface to organic transistor properties: the nature and the role of oxide gate surface defects

Libero Zuppiroli, Stéphane Suarez, Franziska Dora Fleischli

By applying various surface treatments to the oxide gate of pentacene transistors, both in vacuum (H2, O2 and Ar plasma treatments) and in aqueous solution, we were able to vary the balance between oxygen-free radicals (Si•), oxygen-centered radicals (Si−O ...

In situ NMR characterisation of an intermediate in the catalytic hydrogenation of CO2 and HCO3– in aqueous solution

Paul Joseph Dyson, Gabor Laurenczy

The water soluble ruthenium(II) complex [RuCl2(PTA)([9]aneS3)] (PTA = 1,3,5-triaza-7-phosphadamantane, [9]aneS3 = 1,4,7-trithiacyclononane) catalyzes the hydrogenation of CO2 and bicarbonate in aqueous solution. ...

Kinetic studies on the first dihydrogen aquacomplex, [Ru(H2)(H2O)5]2+: Formation under H2 pressure and catalytic H/D isotope exchange in water

André Merbach, Lothar Helm, Gabor Laurenczy, Oleg Yazyev, Pascal Grundler

The ruthenium(II) hexaaqua complex [Ru(H2O)6]2+ reacts with dihydrogen under pressure to give the h2-dihydrogen ruthenium(II) pentaaqua complex [Ru(H2)(H2O)5]2+.The complex was characterized by 1H, 2H and 17O NMR: d H = -7.65 ppm, J HD = 31.2 Hz, d O = -80 ...

Buttressing effects responsible for the meta-deprotonation of trialkylsilyl-substituted haloarenes by organometallic reagents : an unprecedented phenomenon

Christophe Heiss

(2,6-Dichlorophenyl)trimethyl- and triethylsilane exhibit untypical reactivity patterns toward strong bases: when treated at -100 °C with lithium 2,2,6,6-tetramethylpiperidide two, with sec- or tert-butyllithium even three organometallic intermediates are ...
