| titleOfInvention | Method for preparing aliphatic alcohol based on n-butyl lithium |
| abstract | The invention relates to a method for preparing aliphatic alcohol based on n-butyllithium, comprising the steps of mixing borane and aliphatic carboxylic acid in an inert gas atmosphere, adding a catalyst n-butyllithium, and carrying out a hydroboration reaction; and (3) adding silica gel and methanol after the hydroboration reaction is finished, and carrying out hydrolysis reaction to obtain the aliphatic alcohol. 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 0.2 mol% 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 aliphatic alcohols with different substituents under the limited condition is high. |
