| titleOfInvention | Application of anilino lithium compound in catalyzing reaction of carboxylic acid compound and borane hydroboration |
| abstract | The invention discloses an application of an anilino lithium compound in catalyzing a hydroboration reaction of a carboxylic acid compound and borane. And stirring and mixing the catalyst, the borane and the carboxylic acid compound uniformly in sequence, reacting for 35-45 minutes, exposing the mixture to air to terminate the reaction, decompressing the reaction liquid to remove the solvent to obtain the boric acid esters with different substituent groups, wherein the carboxylic acid compound is 1-naphthoic acid, o-carboxyphenylacetic acid, 3-indoleacetic acid, 2-phenylbutyric acid, 3-phenylpropionic acid or diphenylacetic acid. The anilino lithium compound disclosed by the invention can catalyze the hydroboration reaction of carboxylic acid and borane with high activity at room temperature, the dosage of the catalyst is only 0.8mol% of the molar weight of the carboxylic acid, compared with the existing catalytic system, the anilino lithium compound which is a commercial reagent is utilized, the reaction condition is mild, and the yield of borate ester of different substituent groups under the limited condition can reach 99%. |
