Influence of mobile phase acid-base equilibria on the chromatographic behaviour of protolytic compounds

A review about the influence of mobile phase acid-base equilibria on the liquid chromatography retention of protolytic analytes with acid-base properties is presented. The general equations that relate retention to mobile phase pH are derived and the different procedures to measure the pH of the mobile phase are explained. These procedures lead to different pH scales and the relationships between these scales are presented. IUPAC rules for nomenclature of the different pH are also presented. Proposed literature buffers for pH standardization in chromatographic mobile phases are reviewed too. Since relationships between analyte retention and mobile phase pH depends also on the pKa value of the analyte, the solute pKa data in water-organic solvent mixtures more commonly used as chromatographic mobile phase are also reviewed. The solvent properties that produce variation of the pKa values with solvent composition are discussed. Chromatographic examples of the results obtained with the different procedures for pH measurement are presented too. Application to the determination of aqueous pKa values from chromatographic retention data is also critically discussed.

The correlation and prediction of infinite dilution activity coefficients of compounds in water at 298.15 K

We have assembled infinite dilution activity coefficients in water at 298 K for 661 varied compounds. For 655 of these compounds we were able to construct a multiple linear regression equation using Abraham descriptors with a standard deviation of 0.29 log units in log gamma?. Unlike methods such as ASOG or UNIFAC, our equation does not rely on functional groups, and so we can predict further values of activity coefficients for compounds with functional groups not included in the 655 data base. These include ferrocene, terpenes such as alpha-pinene, and compounds containing phosphorous atoms such as trimethylphosphate and dibutylphosphinic acid.

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model.

Iodine(V) reagents in organic synthesis. Part 2. Access to complex molecular architectures via Dess-Martin periodinane-generated o-imidoquinones

o-Imidoquinones, a rather rare class of compounds, are prepared from anilides by the action of Dess-Martin pedodinane (DMP) and water. Their chemistry has been extensively investigated and found to lead to p-quinones and polycyclic systems of diverse molecular architectures. Applications of this methodology to the total synthesis of the naturally occurring compounds, epoxyquinomycin B and BE-10988, are described. Finally, another rare chemical entity, the ketohydroxyamide moiety, has been accessed through this DMP-based synthetic technology, and its reactivity has been studied. Among its most useful reactions is a set of cascade heterocyclic annulations leading to a variety of polycyclic systems of possible biological relevance.

Heat capacities of the six dimethylpyridines between the temperatures 10 K and 445 K and methyl-group rotational barriers in the solid state

Heat capacities and enthalpy increments between the temperatures T = 10 K and 445 K were determined for the six dimethylpyridines by adiabatic calorimetry. (Chemical Abstract registry numbers: 2,3-dimethylpyridine <583-61-9>; 2,4-dimethylpyridine <108-47-4>; 2,5-dimethylpyridine <589-93-5>; 2,6-dimethylpyridine <108-48-5>; 3,4-dimethylpyridine <583-58-4>; and 3,5-dimethylpyridine <591-22-0>.) Triple-point temperatures and enthalpies of fusion are reported for each material, and enthalpy increments and entropies relative to those of the crystals at T -> 0 were derived.Lambda-type phase transitions in the crystals were observed for 2,6-dimethylpyridine and 3,4-dimethylpyridine.A small step or “bump” was observed in the heat-capacity-against-temperature curves for 2,6-dimethylpyridine and 2,3-dimethylpyridine.Barriers to methyl-group rotation in the solid state are estimated for each compound and compared with literature values.
