Title:
USE OF DEPROTONATED PHENYL BRIDGED Β-KETIMINE LITHIUM COMPOUND IN HYDROBORATION REACTION
Document Type and Number:
WIPO Patent Application WO/2021/253847
Kind Code:
A1
Abstract:
Disclosed is the use of a deprotonated phenyl bridged β-ketimine lithium compound in a hydroboration reaction. The hydroboration reaction involves using an ester and a borane as reaction substrates. In the present invention, the deprotonated phenyl bridged β-ketimine lithium compound which is disclosed for the first time is used to catalyze the hydroboration reaction of an ester and a pinacol borane, such that an efficient method for catalyzing hydroboration reactions is developed. The compound has a simple structure and is easy to synthesize, and is capable of catalyzing the hydroboration reaction of an ester and a borane with a high activity. Compared with existing catalytic systems, the amount of the catalyst is reduced, the temperature is milder, and the yield is higher.
