NMR study of the complexation of boric acid with catechol (1,2-dihydroxybenzene) |
|
| Authors: | Maurice Pasdeloup Colette Brisson |
| Abstract: | The boric acid–catechol system in aqueous solutions has been studied by means of 11B, 1H and 13C NMR over wide ranges of concentration and pH. 11B spectra show a striking difference between the complexation possibilities of dilute and more concentrated solutions of boric acid. Both the 1:1 and 1:2 complexes can be simultaneously observed by 13C NMR. |
