Abstract

The boric acid–catechol system in aqueous solutions has been studied by means of ^11^B, ^1^H and ^13^C NMR over wide ranges of concentration and pH. ^11^B 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 ^13^C NMR.

## Abstract The applicability of boric acid catalysis for the direct condensation of carboxylic acids with benzene‐1,2‐diamine to give 2‐substituted benzimidazoles was investigated. It was found that catalytic amounts (5–10 mol‐%) of boric acid efficiently promote the cyclocondensation of aliphatic
