The title compound, [Pd(4)(CH(2))(2)Cl(4)(C(28)H(40)P(2))(2)]·5C(4)H(8)O, possesses a tetra-nuclear palladium core with four bridging chlorido ligands and two bridging methyl-ene units, as well as two bridging anthracene-based bis-phosphine ligands. This tetra-nuclear complex can be considered as being composed of two μ-chlorido-bridged LPd(2) units. The structural motif of these LPd(2) units s...

We have performed the first “high-pressure” XPS study on the palladium, hydrogen and olefin (trans-2-pentene) system in order to gain a better insight into the hydrogenation reaction. We report here data collected using a Pd(111) single crystal and a polycrystalline foil. Hydrogenation was observed on polycrystalline foil (RT and 373 K), but not on Pd(111) single crystal, revealed by on-line ma...

In this paper, a method for the plasma-enhanced (PE) atomic layer deposition (ALD) of palladium on air-exposed, annealed poly(p-xylylene) (Parylene-N, or PPX) is presented. Palladium is successfully deposited on PPX at 80 °C using a remote, inductively coupled, hydrogen/nitrogen plasma with palladium (II) hexafluoroacetylacetonate (Pd(hfac)2) as the precursor. By optimizing the mixture of hydro...

In this review, we summarize our recent development of palladium(0)-catalyzed cross-coupling reactions of perfluoro organic compounds with organometallic reagents. The oxidative addition of a C–F bond of tetrafluoroethylene (TFE) to palladium(0) was promoted by the addition of lithium iodide, affording a trifluorovinyl palladium(II) iodide. Based on this finding, the first palladium-catalyzed c...

The Pd(OAc)(2)/pyridine catalyst system is one of the most convenient and versatile catalyst systems for selective aerobic oxidation of organic substrates. This report describes the catalytic mechanism of Pd(OAc)(2)/pyridine-mediated oxidation of benzyl alcohol, which has been studied by gas-uptake kinetic methods and (1)H NMR spectroscopy. The data reveal that turnover-limiting substrate oxida...

Palladium supported Al2O3 and SiO2 catalysts have been synthesized and evaluated for carbon monoxide oxidation in the presence of ozone. The factors affecting the CO oxidation such as Pd loading (wt%), contact time, reaction temperature and O3/CO molar ratio have been studied. The extent of ozone decomposition on Pd catalysts is proportional to the CO oxidation activity. High reaction temperatu...

An efficient procedure and green route has been developed by using eco-friendly green synthesized palladium nanoparticles (Pd-NPs) as reusable heterogeneous nanocatalyst (Pd@nanocat) for the synthesis of diaryl ethers from the cross coupling reaction of the aryl halides with the phenol in the presence of dimethylsulfoxide (DMSO) as a solvent at 110 oC under natural ligand condition capped Pd-NP...

Glassy carbon foam (GCF) catalyst supports were synthesized from waste polyurethane elastomers by impregnating them in sucrose solution followed pyrolysis and activation (AC) using N2 CO2 gas. The palladium nanoparticles formed Pd(NO3)2. are highly dispersive because the mean diameters 8.0 ± 4.3 (Pd/GCF), 7.6 4.2 (Pd/GCF-AC1) 4.4 1.6 nm (Pd/GCF-AC2). Oxidative post-treatment of resulted formati...

A new binuclear paddle-wheel palladium(II) complex of [Pd2(μ-mtzt)4]dmgH2 (1) has been prepared by the treatment of PdCl2 in acetonitrile with mixture of 1-methyl-1H-1,2,3,4-tetrazole-5-thiol (Hmtzt) and dimethylglyoxime (dmgH2) in methanol. Resulted complex was characterized by elemental analysis (CHNS), IR, UV–Vis absorption, 1H NMR spectroscopy and its structure was determined with single-cr...
