Syntheses, Structures, and Properties of the Dinuclear Copper(II) and Nickel(II) Complexes Bridged by an Alkoxide and a Pyridazine or a Phthalazine

In this paper we report our recent research on the dinuclear copper(II) and nickel(II) complexes 1-10 (Chart 1) containing Schiff bases, derived from acetylacetone, benzoylacetone, or trifluoroacetylacetone, and 1,3-diaminopropane-2-ol. These complexes are bridged by an alkoxide and a pyridazine (pyd) or phthalazine (phta). The magnetic susceptibilities, visible absorption spectra, conductivities, and redox properties of the complexes were investigated and the molecular structures of 2, 4, and 5 are described. The Cu-O-Cu angles found in these complexes indicate a role of the alkoxo-bridge as one of the principal antiferromagnetic exchange pathways. At the same time, the coplanarity of two coordination planes of copper(II) ions is also shown to relate to the exchange process.

Direct C-H arylation of electron-deficient heterocycles with arylboronic acids

A direct arylation of a variety of electron-deficient heterocycles with arylboronic acids has been developed. This new reaction proceeds readily at room temperature using inexpensive reagents: catalytic silver(I) nitrate in the presence of persulfate co-oxidant. The scope with respect to heterocycle and boronic acid coupling partner is broad, and sensitive functional groups are tolerated. This method allows for rapid access to a variety of arylated heterocycles that would be more difficult to access with traditional methods.

Bidentate Lewis acids for the activation of 1,2-diazines – A new mode of catalysis

Bidentate Lewis acids were applied as catalysts for the inverse-electron-demand Diels-Alder (IEDDA) reaction of 1,2-diazines. The concept of catalysis is based on the coordination of the bidentate Lewis acid to both nitrogen atoms of the 1,2-diazine moiety, thereby reducing the electron density and lowering the energy of the LUMO. This should, according to frontier molecular orbital (FMO) theory, facilitate the cycloaddition step. This new concept was successfully applied to a variety of dienophiles and substituted phthalazine substrates. Careful investigations of the mechanism led to the isolation and characterization of key intermediates; all of which support the presented catalytic cycle. Copyright

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: Phthalazine, you can also check out more blogs about253-52-1

In vitro inhibitory effect of quinolinic acid on aldehyde oxidase activity of guinea pig liver: A proposed mechanism

The aim of the present study was to investigate the interaction of quinolinic acid (QA) with partially purified guinea pig liver aldehyde oxidase in terms of superoxide anion production (O2.), hydrogen peroxide (H2O2) formation and the overall substrate oxidation. Due to the structural similarity of QA to some aldehyde oxidase substrates, such as 2-pyrimidinone, the effect of QA on aldehyde oxidase activity has been investigated in the present study. The interaction between QA and aldehyde oxidase has been measured by spectophotometerically and fluorimetrically methods using phthalazine (a classical heterocyclic substrate) and indole-3-aldehyde (an excellent aldehyde substrate). The inhibitory effects of QA on indole-3-aldehyde and phthalazine oxidation, superoxide anion production and hydrogen peroxide formation were found to be competitive inhibition in all three cases (Ki – 77-106 muM, r ? 0.995, p<0.005). QA inhibitory effect on aldehyde oxidase suggests that it may play a role in inhibition of initial rates of superoxide anion formation but may increase overall production of this radical by aldehyde oxidase. QA had a dual effect on superoxide anion production from the two substrates; initial rates were reduced but after 5-8 minutes reaction rates were enhanced. Both effects were concentration dependent. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: Phthalazine, you can also check out more blogs about253-52-1

Quantification of protonation in organic solvents using solution NMR spectroscopy: Implication in salt formation

Purpose Investigate the use of solution NMR spectroscopy to evaluate whether the general DeltapKa rule is valid in organic solvents. Such information may be useful in evaluation of acid-base reactions and solvent selection for salt formation. Methods 1H NMR chemical shift changes in model bases during titration with acids, and separately, on the addition of acids at a molar ratio of 1:1 were determined in water, dimethyl sulfoxide, and methanol. The effect of acid strength on the fraction of ionized base was examined. Results 1H NMR chemical shift changes indicated protonation (in situ salt formation). Different media affected the observed chemical shift changes. In all media investigated the data followed the DeltapKa (base-acid) general rule, that the pKa value of the acids should be 2-3 units lower than the pKa of the base to ensure proton transfer. The addition of water into organic solvents increased the fraction of ionized base. Conclusions Protonation, as measured by chemical shift changes using solution NMR spectroscopy, provided novel insight on potential salt formation in different media. Even though pKa values change with the solvent, the general DeltapKa rule can be applied in different solvent systems. Solution NMR spectroscopy appears to be a useful tool to evaluate salt formation reaction and process control in different solvent systems.
