Acidity Constants of Boronic Acids as Simply as Possible: Experimental, Correlations, and Prediction [PDF]

open access: yesMolecules
The wide use of boronic compounds, especially boronic acids and benzoxaboroles, in virtually all fields of chemistry is related to their specific properties. The most important of them are the ability to form cyclic esters with diols and the complexation

Spectrophotometric determination of the acidity constants of calcon in water and mixed water–organic solvents [PDF]

open access: yesJournal of the Serbian Chemical Society, 2009
The acid–base properties of calcon (1-(2-hydroxy-1-naphthylazo)-2-naphthol-4-sulfonic acid) in water and mixed water–organic solvents at 25 °C at an ionic strength of 0.10 M are studied by a multiwavelength spectrophotometric method. The organic solvents
