Liquid-phase transfer hydrogenation of furfural to furfuryl alcohol on Cu–Mg–Al catalysts
(Elsevier, 2014-08)
The liquid-phase transfer hydrogenation of furfural on Cu-based catalysts was studied. Catalysts were prepared by incipient wetness impregnation (Cu/SiO2) and co-precipitation (Cu–Mg–Al). The effect of metal-support ...
Liquid-phase transfer hydrogenation of furfural to furfuryl alcohol on Cu-Mg-Al catalysts
(Elsevier, 2015-01)
The liquid-phase transfer hydrogenation of furfural on Cu-based catalysts was studied. Catalysts were prepared by incipient wetness impregnation (Cu/SiO2) and co-precipitation (Cu-Mg-Al). The effect of metal-support ...
ULTRASOUND-PROMOTED RAPID and EFFICIENT IODINATION of AROMATIC and HETEROAROMATIC COMPOUNDS in the PRESENCE of IODINE and HYDROGEN PEROXIDE in WATER
(Taylor & Francis Inc, 2014-01-01)
A rapid and efficient ultrasound-promoted protocol for iodination of aromatic and heteroaromatic compounds, using molecular iodine in the presence of aqueous hydrogen peroxide in water without any cosolvent, has produced ...
A Comparison of Homogeneous and Biphasic Hydrogenation Systems of Macrocyclic Lacton with In Situ Formed Rhodium Complexes
(Springer, 2008-12)
Homogeneous and biphasic hydrogenation of avermectins catalyzed by rhodium complexes in situ formed from [RhCl(COD)]2 and triphenylphosphine or sulphonated arylphosphines, respectively, was studied under mild reaction ...
Hydrogenated polycyclic aromatic hydrocarbons (H n PAHs) as catalysts for hydrogenation reactions in the interstellar medium: a quantum chemical model
(Royal Society of Chemistry, 2019-05)
The sticking of H atoms onto dust grains and large hydrocarbon molecules has received considerable attention because it is thought to govern the formation of H2 and other H-containing molecules in the interstellar medium. ...
Hydrogenation of sodium hydrogen carbonate in aqueous phase using metal/activated carbon catalysts
(2018)
The catalytic hydrogenation of sodium hydrogen carbonate in aqueous phase (NaHCO3) to produce sodium formate (or formic acid) on activated carbon-supported metal (Pd, Ru, Ni, Co and Re) species at 25 degrees C and 1 bar ...
Synthesis, structure and catalytic activities for hydrogen transfer reaction of the carbonyl ruthenium(II) complex containing polypyridine and phosphine ligands
(2010)
The synthesis and characterization of new ruthenium(II) carbonyl complexes containing polypyridine and triphenylphosphine ligands is reported. Crystallographic information obtained for the trans-PPh3-[Ru(biq) (PPh3)2(CO)]Cl2 ...
Hydrogenation and isomerization of 1-hexene with Ru-3(CO)(12) and Ru-3(CO)(9)(PPh3)(3)
