Reduction of substituted nitrobenzene derivatives with the formic acid—Triethylamine system, using Pd/SiO2−AlPO4 as catalyst
TLDR
In this article, the liquid phase reduction of different substituted nitrobenzene derivatives with the formic acid-triethylamine system has been carried out by the use of a supported palladium (0,6%) on AlPO4/SIO2 (20:80 weigth) catalyst.Abstract:
The liquid phase reduction of different substituted nitrobenzene derivatives with the formic acid-triethylamine system has been carried out by the use of a supported palladium (0,6%) on AlPO4/SIO2 (20:80 weigth) catalyst. The reduction rate of nitrocompounds containing electron-acceptor substituents is much higher than that of electron donor-containing substrates.read more

New trends in palladium-catalyzed transfer hydrogenations using formic acid
TL;DR: In the presence of a catalytic amount of organic bases, Pd-catalyzed transfer hydrogenations with formic acid were found to be facile processes as discussed by the authors, and the product of the reaction was used to accelerate the transfer hydrogenation process.

Liquid-phase hydrogenation on new AlPO4−SiO2 supported rhodium catalysts
TL;DR: In this article, the liquid phase catalytic hydrogenation of various organic compounds was carried out using new rhodium catalysts supported on AlPO4−SiO2 (20∶80 wt. %) system, in methanol as solvent, under low hydrogen pressure (0.55 MPa) and at 293 K.

Catalytic hydrogenation of cyclohexene: 3. Gas-phase and liquid-phase reaction on supported palladium
E.E. Gonzo,Michel Boudart +1 more
TL;DR: In this paper, the hydrogenation of cyclohexene was studied in both gas and liquid phases on six different palladium catalysts supported on silica gel and alumina between 264 and 308 K at hydrogen pressures from 4 to 89 kPa, cycloxide partial pressure from 0.46 to 1.5 kPa and cycloxide molar concentration of 0.15 to 3.0 M.
