Abstract

0-Formylbenzeneboronic anhydride reacts with aniline, ptoluidine, benzylamine, and n- propylamine to give Schiff bases which are isolated as the trimeric boronic anhydrides. These substances react with catechol to give the catechol derivatives of the boronic acids, in which the boron atom interacts with the neighboring nitrogen atom and becomes tetracovalent. When the free acid, o-formylbenzeneboronic acid, reacts with ...
