Document Type and Number:
WIPO Patent Application WO/2021/253846
Kind Code:
A1
Abstract:
The present invention relates to a lithium compound and a preparation method therefor, and in particular to a deprotonated β-ketimine lithium compound and a preparation method therefor. The method comprises: using m-phenylenediamine and acetylacetone as raw materials to react to prepare a ligand, mixing a small molecular organic lithium solution with a ligand solution, and then reacting to obtain the deprotonated β-ketimine lithium compound. The present invention overcomes the technical prejudice that the prior art focuses on complexes using single negative ion β-ketimine as a skeleton; and a double negative ion β-ketimine complex is disclosed for the first time, filling the blank in the prior art.
