Zusammenfassung: | The present invention relates to applications of a lithium anilide and specifically relates to applications of lithium anilide in catalyzing a hydroboration reaction of imine and borane. A catalyst, borane, and imine are sequentially stirred and mixed evenly, reacted for 1-2 hours, and exposed in air to terminate the reaction; the reaction solution is depressurized to remove a solvent, thus producing borates having different substituents. The lithium anilide disclosed provides high activity in catalyzing the hydroboration reaction of imine and borane at room temperature, the amount of catalyst used is 4-5 mol% of the molar volume of imine, the yield of the reaction is 90% or more, compared with the prior catalyst system, a simple lithium anilide is utilized, reaction conditions are moderate, and the yield of the borates having different substituents under optimized conditions is 99%.
