Catalytic Transfer Hydrogenation of Arenes and Heteroarenes. [PDF]

Chemistry, 2020
AbstractTransfer hydrogenation reactions are of great interest to reduce diverse molecules under mild reaction conditions. To date, this type of reaction has only been successfully applied to alkenes, alkynes and polarized unsaturated compounds such as ketones, imines, pyridines, etc.

Regioselective Synthesis of Alcohols by Catalytic Transfer Hydrogenation of Epoxides. [PDF]

J Org Chem
Reductive ring opening of readily available epoxides provides easy access to synthetically important alcohols. However, controlling the regioselectivity of the reaction under user-friendly conditions remains challenging. Here, we present an efficient methodology for regioselective transfer hydrogenation (TH) of epoxides to synthesize Markovnikov and ...

Catalytic Transfer Hydrogenation Using Biomass as Hydrogen Source

ChemSusChem, 2018
AbstractWe developed an operationally simple method for the direct use of biomass‐derived chemical entities in a fundamentally important process, such as hydrogenation. Various carbohydrates, starch, and lignin were used for stereoselective hydrogenation.

Construction of ionic liquid-Pd/C based bifunction catalysts for the synthesis of UV-P

Journal of Saudi Chemical Society, 2023
Adding light stabilizers to polymeric materials can inhibit or delay the light aging effect and improve the light resistance of materials. 2-(2′-Hydroxy-5′-methylphenyl) benzotriazole (UV-P), as a typical benzotriazole ultraviolet absorber, is widely ...

Catalytic Asymmetric Transfer Hydrogenation of Imines: Recent Advances [PDF]

The Chemical Record, 2015
AbstractIn this review article recent developments in the asymmetric transfer hydrogenation of imines from 2008 up to today are presented. The main methodology involves either metal‐catalyzed procedures in the presence of a chiral ligand or organocatalyzed technologies using a Hantzsch ester and a chiral BINOL‐derived phosphoric acid.

Computational Prediction of Ammonia-Borane Dehydrocoupling and Transfer Hydrogenation of Ketones and Imines Catalyzed by SCS Nickel Pincer Complexes

Frontiers in Chemistry, 2019
Inspired by the catalytic mechanism and active site structure of lactate racemase, three scorpion-like SCS nickel pincer complexes were proposed as potential catalysts for transfer hydrogenation of ketones and imines with ammonia-borane (AB) as the ...

Nickel(II) N-Heterocyclic Carbene Complex for the Hydrogenation of 2-Acetylpyridine under Mild Conditions

Inorganics, 2023
Catalyst-mediated hydrogenation of ketones via hydride transfer can be directly used in the synthesis of alcohols which can exhibit great potential in the practical synthesis of pharmaceuticals. The application of Ni-NHC complexes in the hydrogenation of

Arene-Osmium(II) Complexes in Homogeneous Catalysis

Inorganics, 2021
Although the application of arene-osmium(II) complexes in homogeneous catalysis has been much less studied than that of their ruthenium analogues, different works have shown that, in some instances, a comparable or even superior effectiveness can be ...
