Investigations of reactions of selected azaarenes with radicals in water. 1. Hydroxyl and sulfate radicals

The oxidative degradation of binuclear azaarenes is studied in a number of environmentally relevant radical reactions. The comparison between oxidation mechanisms of hydroxyl and sulfate radicals, as well as between dark and photoreactions, is done. Most of the products formed are identified. With the change from dark to photoreactions of quinoline and isoquinoline, a shift of the oxidation center from the benzene to the pyridine rings is observed. The reaction behavior of the benzodiazines can be derived from the reaction patterns of quinoline and isoquinoline. The rate constants of second order are determined for the reactions of the azaarenes with carbonate radicals. The rate constants and the differences in the products formed conformably prove the importance of the inclusion of excited states in the reaction mechanism. The application of the frontier orbital concept allows an easy interpretation. Electron transfer reactions resulting in radical oxygen species are shown to be product determining in direct photolysis, too.

Ionic liquids are compatible with on-water catalysis

A major limitation of on-water catalysis has been the need for liquid reactants to enable emulsification. We demonstrate that ionic liquids are compatible with on-water catalysis, enabling on-water catalysed reactions for otherwise unreactive solid-solid systems. The unique solvation properties of ionic liquids dramatically expands the scope of on-water catalysis.

Detection of superoxide anion and hydrogen peroxide production by cellular NADPH oxidases

Background The recent recognition that isoforms of the cellular NADPH-dependent oxidases, collectively known as the NOX protein family, participate in a wide range of physiologic and pathophysiologic processes in both the animal and plant kingdoms has stimulated interest in the identification, localization, and quantitation of their products in biological settings. Although several tools for measuring oxidants released extracellularly are available, the specificity and selectivity of the methods for reliable analysis of intracellular oxidants have not matched the enthusiasm for studying NOX proteins. Scope of review Focusing exclusively on superoxide anion and hydrogen peroxide produced by NOX proteins, this review describes the ideal probe for analysis of O2- and H2O2 generated extracellularly and intracellularly by NOX proteins. An overview of the components, organization, and topology of NOX proteins provides a rationale for applying specific probes for use and a context in which to interpret results and thereby construct plausible models linking NOX-derived oxidants to biological responses. The merits and shortcomings of methods currently in use to assess NOX activity are highlighted, and those assays that provide quantitation of superoxide or H2O2 are contrasted with those intended to examine spatial and temporal aspects of NOX activity. Major conclusions Although interest in measuring the extracellular and intracellular products of the NOX protein family is great, robust analytical probes are limited. Several reliable methods for measurement of extracellular O2- and H2O2 by NOX proteins are available.Chemiluminescent probes for both extracellular and intracellular O2- and H2O2 detection have shortcomings that limit their use.Options for quantitation of intracellular O2- and H2O2 are very limited.However, non-redox sensitive probes and genetically encoded reporters promise to provide spatial and temporal detection of O2- and H2O2. General significance The widespread involvement of NOX proteins in many biological processes requires rigorous approaches to the detection, localization, and quantitation of the oxidants produced.

Molecular dynamic and quantum chemical calculations for phthalazine derivatives as corrosion inhibitors of mild steel in 1M HCl

The abilities of phthalazine derivatives, including phthalazine (PT), phthalazone (PTO) and phthalhydrazide (PTD), to inhibit the corrosion of mild steel in 1. M HCl at 30C were studied using electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization measurements. Theoretical calculations were performed to investigate the electronic structures of the PT derivatives. Our results showed that the inhibition efficiencies of these derivatives improved with increases in concentration. The data also showed that PTD < PT < PTO in terms of the inhibiting efficiency. Theoretical calculations also revealed that PTO is expected to be the best inhibitor among the studied phthalazine derivatives. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. 253-52-1, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 253-52-1, in my other articles.

C-H Functionalization of Azines

Azines, which are six-membered aromatic compounds containing one or more nitrogen atoms, serve as ubiquitous structural cores of aromatic species with important applications in biological and materials sciences. Among a variety of synthetic approaches toward azines, C-H functionalization represents the most rapid and atom-economical transformation, and it is advantageous for the late-stage functionalization of azine-containing functional molecules. Since azines have several C-H bonds with different reactivities, the development of new reactions that allow for the functionalization of azines in a regioselective fashion has comprised a central issue. This review describes recent advances in the C-H functionalization of azines categorized as follows: (1) SNAr reactions, (2) radical reactions, (3) deprotonation/functionalization, and (4) metal-catalyzed reactions.

EPR spectral study of copper(II) chelates with hetarylhydrazones of glyoxylic acid

Structure of copper(II) chelates based on glyoxylic hetarylhydrazones containing benzazole (quinoxaline and phthalazine) fragments have been studied by EPR spectroscopy. Spectral parameters in polycrystalline state and dimethylformamide solutions have been determined. Spectral parameters of benzimidazole derivative are typical for square planar structure of the chelate node, while phthalazine derivative displays formation of polymeric structures due to reduction of copper(II) atom.
