| titleOfInvention | Method for preparing boric acid ester by non-catalytic hydroboration reaction of aromatic carboxylic acid |
| abstract | The invention discloses a method for preparing boric acid ester by non-catalytic hydroboration reaction of aromatic carboxylic acid. In an inert gas atmosphere, stirring and uniformly mixing pinacolborane and carboxylic acid in a reaction bottle subjected to dehydration and deoxidation treatment, and reacting for 6-12 hours to obtain boric acid ester; the carboxylic acid is benzoic acid, 4-bromobenzoic acid, 4-fluorobenzoic acid, 1-naphthoic acid, 2-methoxybenzoic acid and the like. The method has the advantages that the carboxylic acid is efficiently subjected to the hydroboration reaction with the borane for the first time under the condition of no catalyst, and a new scheme is provided for the preparation of the boric acid ester by the hydroboration reaction of the carbonyl compound and the borane. |
