Resumen

It is known that a series of organic compounds containing in molecule SH-, NH- qroups, including halogens, carboxylic acids and their derivatives, have the ability to form the innercomplex compounds under certain conditions. These compounds permit to carry out the extraction in acidic medium, that prevents the of process hydrolysis. They are not dissolved in water but are soluble in various solvents and form colored solutions and so may be used as an extractants. The main purpose of this paper is the study of palladium extraction ability for chlorinated naphthenic acids (CNA) synthesited in la

Resumen

SummaryPrevious studies have shown that palladium has toxic effects on the kidney and liver, leads to deterioration of the general condition of animals, and could cause allergy in animals and humans. Considering the limited data about the influence of palladium on the cardiovascular system, the aim of our study was to evaluate the effects of palladium on the heart from available published data, and to compare the toxicity of inorganic and organic palladium compounds. Relevant studies for our review were identified from PubMed and Scopus databases. The search terms included »palladium «, »palla

Resumen

ABSTRACTEthidium 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 quantification of targeted live cells, fewer laborious procedures, lower costs, and potentially higher-throughput analysis than the use of EMA and PMA. We have also recently reported platinum compoun

Resumen

In palladium refining technologies, as well as in some analytical procedures, complexes of bivalent palladium with diimines, amines, oximes, thiourea, and other compounds are used. In the technologies used, complex compounds of palladium are subjected to thermal decomposition, during which metallic palladium is formed. The precious metals market is seeing a rapid rise in the price of palladium on the back of a rapid increase in demand for it. It has been experimentally shown that active decomposition of dichlorodiamminepalladium Pd(NH3)2Cl2 and dimethylglyoximpalladium (C4H7N2O2)2Pd occurs at

Resumen

AbstractIn this research, a recycling process for palladium using “dry aqua regia,” which consists of iron(III) chloride–potassium chloride, was proposed. Palladium was dissolved in “dry aqua regia,” and the dissolved palladium was recovered by leaching with potassium chloride solution with added ammonium chloride and nitric acid. Palladium was almost completely dissolved in 3 h at 600 K, and the recovery ratio of dissolved palladium was up to 80%. In addition, the dissolution of palladium in coexistence with platinum and the dissolution of platinum-palladium alloy by “dry aqua regia” were als

Resumen

The structure of the (1,3-butadiene)M(R2PC2H4PR2) compounds (M = Ni, Pd, Pt; R = Pri, Bu′, Cy) in the solid-state have been investigated by 13C and 31P CP/MAS NMR spectroscopy. The bonding mode adopted by the diene is dependent upon the nature of the metal: the palladium compounds contain an η2-diene molecule, the nickel compound where R is cyclohexyl contains an η4-diene molecule whereas the Pr2iPC2H4PPr2i-stabilized platinum compound con- tains a platinacyclopentene ring. The crystal structures of (η2-1,3-C4H6)Pd(Cy2PC2H4PCy2) and (η4-1,3-C4H6)Ni(Cy2PC2H4PCy2) have been confirmed by X-ray di

Starting from γ-ketoesters with an o-iodobenzyl group we studied a palladium-catalyzed cyclization process that stereoselectively led to bi- and tricyclic compounds in moderate to excellent yields. Four X-ray crystal structure analyses unequivocally defined the structure of crucial cyclization products. The relative configuration of the precursor compounds is essentially transferred to that of the products and the formed hydroxy group in the newly generated cyclohexane ring is consistently in trans-arrangement with respect to the methoxycarbonyl group.

AbstractCarbonylation, one of the most powerful approaches to the preparation of carbonylated compounds, has received significant attention from researchers active in various fields. Indeed, impressive progress has been made on this subject over the past few decades. Among the various types of carbonylation reactions, asymmetric carbonylation is a straightforward methodology for constructing chiral compounds. Although rhodium-catalyzed enantioselective hydroformylations have been discussed in several elegant reviews, a general review on palladium-catalyzed asymmetric carbonylations is still mi

Resumen

This paper presents the results of a study on the catalytic activity and selectivity of nickel and palladium catalysts in hydrogenation reactions of nitro- and acetylene compounds. It was shown that the activity and selectivity of nickel catalysts in the hydrogenation of phenylacetylene depend on the nature of modifying additives (Cu, Zn, Ti, Cr, Bi, Ti–Cu, Mn, Fe), and the activity and selectivity of palladium catalysts based on a polymer of metal complexes depends on the method of their preparation. It was found that for certain concentrations of the active phase of palladium (0.8 wt.%) and

Resumen

A variety of chromone-containing polycyclic compounds are efficiently constructed in good yields with excellent diastereoselectivities via palladium-catalyzed [2 + 2 + 1] annulation of 3-iodochromones, α-bromo carbonyl compounds, and tetracyclododecene.

Resumen

Background: Aryl-methoxybenzaldehydes substituted in various positions may serve as valuable starting materials for the synthesis of biologically active compounds. Methods: Biaryl-methoxybenzaldehydes and pyridyl-aryl-methoxybenzaldehydes were synthesized by the Suzuki-Miyaura cross-coupling reactions as intermediates of potential drug substances. Three different catalytic approaches were compared. The classical Suzuki method utilising tetrakis(triphenylphosphine)palladium and sodium ethoxide, the protocol applying palladium acetate and tri(o-tolyl)phosphine, and the method using tetrakis(trip

Resumen

Palladium complexes of two different P,N ligands (a phosphane-pyridine and a phosphane-imine ligand) were synthesized and characterized. Single crystal X-ray structure analyses of the palladium diiodide compounds revealed a square-planar coordination geometry at the metal center with a longer Pd-I bond in trans-position to the phosphorus atom. The chloro-methyl palladium species of the phosphane-pyridine ligand was applied for the oligomerization of ethene using a borate salt as cocatalyst.

Resumen

An efficient chemoselective reduction of aromatic nitro compounds to corresponding amino analogs was achieved using palladium doped TiO2 (Ti0.97Pd0.03O1.97) nanoparticles. The reductions are effectively carried out in the presence of aromatic nitro compounds of various other reducible functional groups such as halo, alkoxy, carbonyl, and cyanide. The reduction of aromatic nitro compounds to aromatic amines was recognized with excellent yield (100%) by using nano porous palladium as a sustainable catalyst and as a hydrogen source. Reduced amines were well characterized using PXRD, 1H NMR, and 1

Resumen

AbstractSonolysis of aqueous solution of chlorobenzene at 200 kHz frequency in the presence of transition metals chlorides was investigated. Through analyzing the nature and distribution of the products detected in the reaction mixture, a new mechanism of sonodegradation is advanced. Depending on the metals used and their behavior during sonolysis, we were able to discriminate between inside and outside cavitation bubble mechanisms. Iron and cobalt chlorides, which could undergo redox reactions in the presence of HO radicals generated ultrasonically, give higher amounts of phenolic compounds c

Resumen

The transition-metal catalyzed addition of heteroatom nucleophiles to aryl and vinyl halides is reviewed. This chemistry typically involves a nickel- or palladium-based catalyst containing phosphine ligands. In recently developed palladium-catalyzed chemistry, aryl halides react with amines in the presence of base to form arylamines. In similar chemistry catalyzed by both nickel and palladium, aryl and vinyl halides react with alkali metal or tin thiolates or selenides to form aryl and vinyl sulfides, while the reaction of different phosphorus compounds, such as phosphides, phosphonates, and
