Pyridinecarbothionylaminopyridines as structural isomers were obtained by the reactions of 2,3-and 2-4-lutidine with aminopyridines and sulfur. Reaction of 2,6-lutidine with active methyl group anilines in the presence of sulfur gave the desired thioamides 5. Reaction of synthesized thioamides 5 with sulfur and SiO2 or SeO2 gave the corresponding amide 6. We now report conversion of thioamide to amide by using oxidizing inorganic reagent.

A series of porphyrins containing methoxy-substituted phenols were treated with different pyridine bases. Besides hydrogen bonding (H-bonding), the pyridine bases have imparted oxidation to the phenol rings resulting in coupled electron and proton movement. It has been shown that reduction of an excited substrate/porphyrin macrocycle by phenols with adjacent methoxy groups is facilitated by the movement or transfer of the phenolic proton toward H-bonded bases. Rates of electron transfer are accomplished by associated proton displacements within the redox reaction complex. Demonstrated fluorescence quenching of meso-(4-hydroxyphenyl derivatives)-substituted porphyrins in aprotic solvents is attributed to electron transfer from the phenol moiety by added bases (different pyridine derivatives), and rates of quenching are found to be correlated with Broensted base strength rather than H-bonding equilibria. The rate of quenching is observed to be a function of the extent of hydroxy and methoxy substitutions to the phenyls and the solvent polarities. Replacement of 4-hydroxy by 4-methoxy completely eliminated the quenching indicating the disappearance of reduction in the porphyrin macrocycle. The dependence of the extent of fluorescence quenching of studied porphyrins on pyridine concentration led to phenol-pyridine H-bonding equilibrium constants, and these values closely resemble the values obtained directly from the corresponding absorption spectra. The quenching agent is thus revealed to be H-bonded phenol. Further, positive deuterium isotope effects on quenching upon deuteration of the hydroxyl confirm that the electron transfer is coupled to the proton movement.

Copper(II) acetate reacts with pyridine and quinoline bases in dioxane giving rise to adduct compounds, which were characterized by UV and EPR techniques.The reaction is formulated as follows: Cu2(OAc)4+L<*>Cu2(OAc)HL, where L denotes a free base and K21 is an adduct formation constant.Values of K21 range from 12 for quinoline or 2-picoline to 146 mol-1 dm-3 for 4-ethylpyridine.A linear free energy relationship is observed between the adduct formation and the protonation of bases in water except for sterically crowded bases.

The IS-CE method is developed for pKa determination of polyprotic compounds. In this method, the internal standard (IS) and the polyprotic test compound are injected into the capillary electrophoresis (CE) system in buffers with appropriate pH. The pH of the buffers is not externally measured, but determined inside the capillary from the mobilities of the internal standards. Then the pKa values of the polyprotic compounds are obtained by fitting its mobilities to the in situ pH values. The method is faster than the classical CE method (a diprotic compound can be done in less than 15min), and also than other methods like potentiometric and spectrophotometric titrations. The method has been successfully applied to 20 polyprotic test compounds of different chemical nature, including compounds with extreme or very close pKa values.

Monitoring of target analytes (e.g., pharmaceuticals, endogenous compounds) present in biological samples usually requires a preliminary step toward analyte isolation from surrounding matrix and enrichment for trace analysis. Evident developments have been recently made to introduce novel ?green? analytical approaches (which keep the requirements of Green Analytical Chemistry ? GAC) being effective, economical, eco-friendly, and amenable to hyphenated analytical instrumentations. Modern membrane-based extraction techniques provide the smart options against classical sample preparations e.g., liquid-liquid extraction (LLE).These approaches are more stable and allow trace determination of analytes in complex matrices (e.g., biological samples), with high extraction recovery and selectivity. Simultaneously, drawbacks of LLE such as large consumption of organic solvents and the need for tedious handling are eliminated. This paper thoroughly overviews important features and applications of membrane- based extraction techniques with special focus on pharmaceutical and biomedical analysis since 2013. Different driving forces of mass transfer across the membrane were summarized and membrane-based extraction techniques were described along with their advantages/disadvantages as well.
