In chemistry, transfer hydrogenation is a chemical reaction involving the addition of hydrogen to a compound from a source other than molecular H 2. It is applied in laboratory and industrial organic synthesis to saturate organic compounds and reduce ketones to alcohols , and imines to amines .
An alternative, innovative and highly promising approach to convert LOHC-bound hydrogen into electricity is proposed recently. [1] The new unloading sequence consists of an almost thermoneutral catalysed transfer hydrogenation step converting ketone to secondary alcohol by contacting hydrogen-rich carrier (H18-DBT), and the secondary alcohol is then directly consumed in a PEMFC (direct ...
The Guerbet reaction, reported in 1899, [5] is an early example of a hydrogen auto-transfer process. The Guerbet reaction converts primary alcohols to β-alkylated dimers via alcohol dehydrogenation followed by aldol condensation and reduction of the resulting enones.
Hydrogenation is a chemical reaction between molecular hydrogen (H 2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule ...
The reaction of diphenylacetylene and Ru 3 (CO) 12 gives the piano stool complex (Ph 4 C 4 CO)Ru(CO) 3). Subsequent hydrogenation of this tricarbonyl affords Shvo's catalyst. [2] [3] The iron analogue is also known, see Knölker complex. The compound contains a pair of equivalent Ru centres that are bridged by a strong hydrogen bond and a ...
Reductions with hydrosilanes are methods used for hydrogenation and hydrogenolysis of organic compounds.The approach is a subset of ionic hydrogenation.In this particular method, the substrate is treated with a hydrosilane and auxiliary reagent, often a strong acid, resulting in formal transfer of hydride from silicon to carbon. [1]
Shuttle catalysis is used to describe catalytic reactions where a chemical entity of a donor molecule is transferred to an acceptor molecule. [1] In these reactions, while the number of chemical bonds of each reactant changes, the types and total number of chemical bonds remain constant over the course of the reaction.
The Bamberger rearrangement is the chemical reaction of phenylhydroxylamines with strong aqueous acid, which will rearrange to give 4-aminophenols. [1] It is named for the German chemist Eugen Bamberger (1857–1932).
