Palladium nanoparticles supported on mesoporous natural phosphate: An efficient recyclable catalyst for nitroarene reduction

We report the preparation of palladium nanoparticles supported on mesoporous natural phosphate (Pd@NP) using a wetness impregnation method. The prepared catalyst was characterized using various techniques. Furthermore, the reduction and preparation of the palladium nanoparticles was followed using UV–visible spectra. Based on the Scherrer equation, the crystallite size of the as-synthesized palladium nanoparticles was 10.88?nm. The performance of the synthesized catalyst was investigated in the reduction of 4-nitrophenol as a model substrate to 4-aminophenol using NaBH4 as a hydrogen source. Moreover, catalytic reduction of various nitroarenes was studied and monitored using UV–visible spectroscopy and gas chromatography. The Pd@NP catalyst showed a high activity for the selected reaction and could be recycled.

Binuclear half-sandwich ruthenium(II) Schiff base complexes: Synthesis, characterization, DFT study and catalytic activity for the reduction of nitroarenes

The binuclear ruthenium(II) p-cymene complexes containing Schiff base ligands of general composition [(Ru(p-cymene)Cl)2L1-6] (1-6) have been synthesized. The complexes were characterized by analytical and spectral (FT?IR, UV–Vis & 1H NMR) methods. The molecular structure of the representative complex [(Ru(p-cymene)Cl)2(L6)] (6) was determined by single-crystal X-ray diffraction and density functional theory (DFT) calculations. Further, these half-sandwich ruthenium complexes are active catalysts for the mild hydrogenation of nitroarenes to aromatic anilines in the presence of NaBH4 in ethanol. The most efficient catalyst 6, was found be compatible with nitroarenes of various functional groups.

Selective reduction of nitro compounds using CeY zeolite under microwaves

Aliphatic and aromatic nitro compounds were selectively reduced to their corresponding amino derivatives in good yields using formic acid and CeY zeolite under monomode reactor. This system is found to be compatible with several sensitive functionalities. Beside the recycling result showed it had a long catalyst lifetime and could maintain activity even after being used for 20 cycles.

The reduction can be carrid out not only with HCOOH but also with HCOONH4.

Amino-benzoic acids and derivatives, and methods of use

The present invention relates to compounds, compositions and methods for inhibiting nonenzymatic cross-linking (protein aging). Accordingly, a composition is disclosed which comprises an agent capable of inhibiting the formation of advanced glycosylation endproducts of target proteins by reacting with a carbonyl moiety of the early glycosylation product of such target proteins formed by their initial glycosylation. The method comprises contacting the target protein with the composition. Both industrial and therapeutic applications for the invention are envisioned, as food spoilage and animal protein aging can be treated.
