Transfer Hydrogenation. Transfer hydrogenation is not limited to anilines as substituted thiophenols phenols and carboxylic acids are competent proton sources as well resulting in complete reduction of the olefin in less than 1 h table 2 entries 38. Catalytic transfer hydrogenationhydrogenolysis is economically and environmentally benign synthetic strategies to valorize renewable compounds derived from biomass.
Herein we have realized heterogeneous photocatalytic chemoselective transfer hydrogenation reaction of quinolines to their corresponding tetrahydroquinolines over the developed hierarchical nioin 2 o 3 cds microspheres with high activity and selectivity under visible light irradiation and mild conditions in which benzyl alcohol serves as a hydrogen donor. Of all the as prepared catalysts bimetallic cu pd catalysts showed th. Simple and easily accessible organic molecules such as eg.
Transfer hydrogenation catalysts that are tailor made to work under speci c conditions is a great asset to anyone working in synthetic organic chemistry.
The sequential transfer hydrogenationhydrogenolysis of furfural and 5 hydroxymethylfurfural to 2 methylfuran and 25 dimethylfuran is studied over in situ reduced fe 2 o 3 supported cu ni and pd catalysts with 2 propanol as hydrogen donor. In this work 25 dimethylfuran dmf production through catalytic transfer hydrogenation of 5 hydroxymethylfurfural 5 hmf in liquid phase was investigated over ternary cu x znal catalysts using isopropanol as hydrogen donor. Asymmetric transfer hydrogenation of ketones as an effi cient synthetic route to optically active alcohols has attract ed increasing attention in the last decade due to its great po tential for applications in the fine chemical pharmaceutical agrochemical industries. Herein we have realized heterogeneous photocatalytic chemoselective transfer hydrogenation reaction of quinolines to their corresponding tetrahydroquinolines over the developed hierarchical nioin 2 o 3 cds microspheres with high activity and selectivity under visible light irradiation and mild conditions in which benzyl alcohol serves as a hydrogen donor.
