Sole, Roberto; Buranello, Chiara; Bardella, Noemi; Di Michele, Alessandro; Paganelli, Stefano; Beghetto, Valentina published their research in Catalysts in 2021. The article was titled 《Recyclable Ir Nanoparticles for the Catalytic Hydrogenation of Biomass-Derived Carbonyl Compounds》.Recommanded Product: Ethyl 5-bromovalerate The article contains the following contents:
The valorisation of biomass-derived platform chems. via catalytic hydrogenation is an eco-friendly tool which allows authors to recover bio-based building blocks and produce fine chems. with high industrial appeal. In the present study, a novel surfactant-type triazolyl-thioether ligand was prepared, showing excellent catalytic activity in the presence of bis(1,5-cyclooctadiene)diiridium(I) dichloride [Ir(COD)Cl]2 for the hydrogenation of furfural, cinnamaldehyde, levulinic acid, 5-hydroxymethylfurfural, vanillin, and citral. Easy recovery by liquid/liquid extraction allowed authors to recover the catalyst, which could then be efficiently recycled up to 11 times for the hydrogenation of furfural. In-depth anal. revealed the formation of spherical structures with metal nanoparticles as big as 2-6 nm surrounded by the anionic ligand, preventing iridium nanoparticle degradation In the experiment, the researchers used Ethyl 5-bromovalerate(cas: 14660-52-7Recommanded Product: Ethyl 5-bromovalerate)
Ethyl 5-bromovalerate(cas: 14660-52-7) belongs to bromides. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents.Recommanded Product: Ethyl 5-bromovalerate
