Application of lithium 4-methoxyaniline in catalysis of hydroboration reaction of imine and borane
11891408 · 2024-02-06 · ·

The present invention relates to the application of lithium 4-methoxyaniline in catalysis of the hydroboration reaction of an imine and a borane. A catalyst, a borane and an imine are successively stirred and mixed until uniform, reacted for 1 to 2 hours, and then exposed to air so as to stop the reaction, and the reaction liquid is subjected to decompression to remove a solvent therein, so as to obtain a borate with different substituents. The lithium 4-methoxyaniline disclosed in the present invention can catalyze the hydroboration reaction of an imine and a borane in a high activity manner at room temperature, wherein the amount of the catalyst is merely 4-5 mol % of the molar amount of the imine, and the yield of the reaction can reach 90% or more. The yield of a borate with different substituents can reach 99% with mild reaction conditions under an optimized condition.
