Palladium-based carbon catalysts (Pd/C) can be potentially applied as an efficient catalyst for Suzuki–Miyaura and Mizoroki–Heck coupling reactions. Herein, a variety of palladium on activated were prepared by varying the content ‘Pd’ via in situ reduction method, using hydrogen reducing agent. The as-prepared (0.5 wt % Pd/C, 1 2 Pd/C 3 Pd/C) characterized X-ray diffraction (XRD), scanning elec...

BACKGROUND The anticancer properties of cisplatin and palladium(II) complexes stem from the ability of the cis-MCl2 fragment to bind to DNA bases. However, cisplatin also interacts with non-cancer cells, mainly through bonding molecules containing -SH groups, resulting in nephrotoxicity. This has aroused interest in the design of palladium(II) complexes of improved activity and lower toxicity. ...

Palladium nanoparticles made by atomic layer deposition (ALD) normally involve formaldehyde or H2 as a reducing agent. Since is toxic and explosive, it advantageous to remove this step during the fabrication of palladium metal ALD. In work we have successfully used Pd(hfac)2 ozone directly prepare nanoparticles, without use annealing agents. Density functional theory (DFT) was employed explore ...

The Palladium inserted hydridopalladium species represents as RCOOPdH. This work finds an interesting coupling of palladium RCOOPdH with potassium styryltrifluoroborates to synthesize new kinds styryl ester compounds. Pd(OAc)2 was most effective catalyst for this cross-coupling reaction under microwave irradiation and gave esters in good moderate yields.

The adsorption of ethylene on gold–palladium alloys formed on a Pd(111) surface is investigated using a combination of temperature-programmed desorption (TPD) and reflection absorption infrared spectroscopy (RAIRS). Various alloy compositions are obtained by depositing four monolayers of gold on a clean Pd(111) surface and annealing to various temperatures. For gold coverages greater than 0.7, ...

The role of palladium surface oxides and adsorbed oxygen in the analytical performance Pd-NPs-based nanobiosensors is ascertained.

Catalysis by palladium derivatives is now one of the most important tools in organic synthesis. Whether researchers design palladium nanoparticles (NPs) or nanoparticles occur as palladium complexes decompose, these structures can serve as central precatalysts in common carbon-carbon bond formation. Palladium NPs are also valuable alternatives to molecular catalysts because they do not require ...

Palladium nanoparticles encapsulated into graphite (Pd–graphite intercalation compound: Pd–GIC) were produced from two kinds of graphite, natural graphite (average flake size: 270 mm) and kish graphite (average flake size: 15 mm). Hydrogen storage properties of Pd– GIC have been investigated by means of differential scanning calorimetry (DSC) between 473 and 573 K at 1.0 MPa hydrogen pressure. ...

Submitted: Jul 13, 2013; Accepted: Aug 26, 2013; Published: Aug 29, 2013 Abstract: Two new arylene diamines compounds have been synthesized via palladium-catalyzed reaction of 1,4-phenylenediamine with two aromatic dibromides. This one-pot reaction was based on using the catalyzed system resulting from Pd / BINAP, Pd / di-t-butylphosphinobiphenyl, Pd / P(t-Bu) , Pd / 1,3-bis(2,63 diisopropylphe...

Polynuclear Pd(II) complexes with biogenic polyamines present great potential clinical importance, due to their antiproliferative and cytotoxic activity coupled to less severe side-effects. The adsorption process and the redox behaviour of two polynuclear palladium chelates with spermine (Spm) and spermidine (Spd), Pd(II)-Spm and Pd(II)-Spd, as well as of their ligands Spm and Spd, were studied...
