Solubilities are reported for aluminum, gallium, and indium tris-ligand complexes of the pyrones maltol and ethylmaltol and of a number of 4-pyridinones in water–methanol and water–tert-butyl alcohol solvent mixtures, at 298.2 K. Trends and patterns in transfer chemical potentials derived from these solubilities are discussed in terms of the dependence of solvation on the nature of the ligand, the metal, and the cosolvent.

The reaction between 2,2-di(4-nitrophenyl) 1,1,1-trifluoroethane and excess sodium tert-butoxide in tert-butyl alcohol takes place rapidly to yield first the olefin, by elimination of HF. This is followed by a slower addition of tert-butoxide to the olefin, which upon reaction with the solvent gives the tert-butyl ether as the final product. The blue anions involved in each of these reactions are observed.Rate constants, the primary deuterium kinetic isotope effects, and the activation parameters have been measured for the appearance of the initial blue colour and also for the formation of the olefin. It is concluded that the reaction proceeds by a reversible ElcB mechanism.

We have measured the viscosity coefficient B of the electrolytes NaCl and Bu4NBr in aqueous-organic mixtures containing up to 40% by weight of tert-butyl alcohol (TBA), as well as that of the non-electrolyte TBA in aqueous solutions of the salts NaCl and Bu4NBr. The variations of B were compared with those of the thermodynamic quantities ΔHtθ and ΔStθ of the solutes studied in these different media. The contribution of the solute to the free enthalpy of activation of viscosity has also been calculated.
