Emerging progress in ruthenium-catalyzed transfer and asymmetric transfer hydrogenation [PDF]

RSC Advances
Ruthenium-catalysed transfer hydrogenation (TH) and asymmetric transfer hydrogenation (ATH) are well recognised as efficient and environmentally benign methods for synthesising chiral alcohols, amines, and key intermediates used in the pharmaceutical and

Decatungstate-photocatalyzed transfer hydrogenation of unsaturated compounds using alcohol as the hydrogen source [PDF]

Nature Communications
We present a simple and efficient photocatalytic method for the transfer hydrogenation of unsaturated compounds using alcohol as the hydrogen source and low-cost decatungstate as the photocatalyst.

Selective hydrogenation of α,β[alpha,beta]-unsaturated aldehydes towards clean synthesis over noble metal catalysts in mass transfer efficient three phase reactors [PDF]

, 1998
The hydrodynamics and mass transfer characteristics of a concurrent downflow contactor (CDC) are studied in this work in order to investigate the viability of this bubble column as a catalytic reactor for the hydrogenation of α,β-unsaturated aldehydes ...

Tetrahydroxydiboron-Mediated Palladium-Catalyzed Deoxygenative Transfer Hydrogenation of Aryl Ketones [PDF]

, 2022
We describe a palladium-catalyzed deoxygenative transfer hydrogenation of ketones using B2(OH)4 as the sole additive. Deuterium labeling experiments using B2(OD)4 show that the incorporated protons originate exclusively from the diboron reagent ...

Ruthenacycles and Iridacycles as Catalysts for Asymmetric Transfer Hydrogenation and Racemisation [PDF]

, 2010
Ruthenacycles, which are easily prepared in a single step by reaction between enantiopure aromatic amines and [Ru(arene)Cl2]2 in the presence of NaOH and KPF6, are very good asymmetric transfer hydrogenation catalysts.

Selective hydrogenation in trickle-bed reactor. Experimental and modelling including partial wetting. [PDF]

, 2003
A steady state model of a trickle bed reactor is developed for the consecutive hydrogenation of 1,5,9-cyclododecatriene on a Pd/Al2O3 catalyst. Various experiments have shown that the selectivity of this reaction towards the product of interest is much ...
