| titleOfInvention | Method for preparing borate based on n-butyl lithium |
| abstract | The invention relates to application of n-butyllithium, in particular to a method for preparing borate based on n-butyllithium. And stirring and mixing the catalyst, the borane and the carboxylic acid uniformly in sequence, reacting for 40-50 minutes, exposing the mixture to air to terminate the reaction, and decompressing the reaction liquid to remove the solvent to obtain the borate with different substituent groups. The n-butyllithium 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 0.5mol% of the molar weight of the carboxylic acid, compared with the existing catalytic system, the commercial reagent n-butyllithium is utilized, the reaction condition is mild, and the yield of borate ester of different substituents can reach 99% under the limited condition. |
