Bimetallic Transition Metal Hydride Complexes

Russian Chemical Reviews, 1983
The literature data on bimetallic transition metal hydride complexes containing metal–hydrogen bonds and non-transition metal atoms are described systematically and discussed. The principal methods of synthesis of these compounds and ways of stabilising them in the lowest oxidation state by cyclopentadienyl and other electron-donating ligands are ...

Complex Transition Metal Hydrides

Angewandte Chemie International Edition in English, 1988
AbstractCompounds having structural units formed by transition metals and hydrogen have only become known fairly recently. Only the synthesis and structural characterization of ternary metal hydrides AxMyHz in which A is an alkali or alkaline‐earth metal and M is a transition metal, led to the discovery of anionic complex groups of the form [MHz ...

The stereochemistry of reduction by complex metal hydrides

Experientia, 1960
Die gegenwartig akzeptierte Theorie des Mechanismus der Reduktion von Ketonen mit Metallhydriden wird diskutiert. Verschiedene Unstimmigkeiten werden aufgezeigt, und ein neuer Mechanismus wird vorgeschlagen, der mit den experimentellen Befunden besser ubereinstimmt.

Hydrogen storage and evolution catalysed by metal hydride complexes

Dalton Trans., 2013
The storage and evolution of hydrogen are catalysed by appropriate metal hydride complexes. Hydrogenation of carbon dioxide by hydrogen is catalysed by a [C,N] cyclometalated organoiridium complex, [Ir(III)(Cp*)(4-(1H-pyrazol-1-yl-κN(2))benzoic acid-κC(3))(OH(2))](2)SO(4) [Ir-OH(2)](2)SO(4), under atmospheric pressure of H(2) and CO(2) in weakly basic ...

Hydride transfer reactions catalysed by metal complexes

Journal of the Chemical Society B: Physical Organic, 1966
IN the course of an investigation of the catalytic action of certain metal complexes in hydride transfer reactions it was observed that rhodium chloride catalysed the dehydrogenation of isopropanol to acetone. During the reaction rhodium metal was precipitated, and it was found that the rate of dehydrogenation decreased as rhodium was removed from ...

Synthesis of Metal Complex Hydrides for Hydrogen Storage

The Journal of Physical Chemistry C, 2007
A new procedure for the direct synthesis of metal complex hydrides, NaAlH4 and LiAlH4, has been developed through hydrogenation of their respective metal hydrides, NaH and LiH, with Al, both in the presence of a catalyst and in the presence of a liquid complexing agent.

Complex Ternary Transition-Metal Hydrides and Hydridometalates

2013
Various preparation routes led to a large number of complex ternary transition-metal hydrides and hydridometalates containing d- and f-elements, together with alkali, alkaline-earth, and rare-earth metals. Here, the parameter pressure is a crucial tool for the selective synthesis: increasing the reaction pressure leads to higher oxidation states of the

The Reduction of Nitrogen Heterocycles with Complex Metal Hydrides

1966
Publisher Summary The reactions of complex metal hydrides occur by an attack of the nucleophilic hydride ion on an electrophilic center. Aromatic nitrogen heterocycles in which the nitrogen contributes only one electron to the π-system are electrophilic as compared to benzene, and show a reduction by lithium aluminum hydride, an active reducing agent.
