Four new metal complexes {M = Pd(II) or Pt(II)} containing the ligand 9-aminoacridine (9AA) were prepared. The compounds were characterized by FT-IR and (1)H, (13)C, and (195)Pt NMR spectroscopies. Crystal structure of the palladium complex of formulae [Pd(9AA)(mu-Cl)](2) . 2DMF was determined by X-ray diffraction. Two 9-acridine molecules in the imine form bind symmetrically to the metal ions ...

The coadsorption of nitric oxide and carbon monoxide on Pd( loo), Pd( 11 l ) , and a model silica-supported palladium catalyst has been investigated with infrared reflection-absorption spectroscopy (IRAS) in the temperature range 100-500 K. The palladium surfaces were in equilibrium with a 1 X l P Torr equimolar mixture of CO and NO during the FT-IRAS studies. The structure and coverage of the ...

The enantioselective Pd-catalyzed allylation reaction of fluorinated allyl enol carbonates is presented; a key feature of this transformation is the important effect of the ligand-to-palladium ratio on the enantioselectivity of the alpha-fluoroketones, since using a ligand excess (L/Pd ratio = 1.25 : 1) led to moderate results (30-76% ee), while using a L/Pd ratio <1 : 1.67 (to as low as 1 : 4)...

The reaction of molecular oxygen with palladium(0) centers is a key step in Pd-catalyzed aerobic oxidation reactions. The present study provides a density functional theory (DFT) computational analysis of the mechanism and electronic structural features of the reversible, associative exchange between O(2) and ethylene at an ethylenediamine (en)-coordinated palladium(0) center. Salient features ...

A new complex of palladium was isolated with 2-furoic hydrazide (FH) and characterized by spectroscopic methods. The results show that the ligand is coordinated to palladium by the basic nitrogen of NH2 group and has a general structure of type cis-[Pd(FH)2Cl2]. The structure of palladium(II) complex was optimized and theoretical data show good agreement with the experimental results. The cytot...

Abstract In this study , palladium nano-particles were electro deposited galvano - statically on carbon black powder (Vulcan XC -72R). The catalytic activity for electro - oxidation of ethanol and methanol in alkaline media were studied by cyclic voltammetry and linear sweep voltammetry techniques. The results indicated that the electro-oxidation of ethanol and methanol strongly depends o...

Ethidium monoazide and propidium monoazide (EMA and PMA) have been used in combination with PCR for more than a decade to facilitate the discrimination of live and dead bacteria (LD discrimination). These methods, however, require many laborious procedures, including the use of a darkroom. Here, we demonstrate an innovative use of palladium compounds involving lower limits of detection and quan...

Using ab-initio calculations and kinetic Monte Carlo simulations, we demonstrate that the deposition geometries of palladium are strongly dependent on the polarization direction of the LiNbO3 substrate. Different stoichiometries and atomic structures of the positively and the negatively polarized substrates cause substantially different bonding configurations of palladium and energy barriers fo...

A large collection of palladium samples, supplied by IMRA Materials (Japan), were studied to determine the relationship between energy production and various properties including the amount of excess volume, the open-circuit-voltage, and the maximum D/Pd ratio. The following conclusions result from the work: 1. Palladium, no matter how well prepared, is very inhomogeneous with respect to the pr...
