Deprotonated beta-ketimine lithium compound and preparation method thereof

The invention relates to a lithium compound and a preparation method thereof, in particular to a deprotonated beta-ketimine lithium compound and a preparation method thereof. The preparation method comprises the following steps: taking 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 beta-ketimine lithium compound. The technical prejudice that the method in the prior art focuses on complexes with single negative ion beta-ketimine as a skeleton is overcome, the double negative ion beta-ketimino complex is disclosed for the first time, and the blank in the prior art is filled. 本发明涉及一种锂化合物及其制备方法，具体涉及一种脱质子β-酮亚胺锂化合物及其制备方法。以间苯二胺、乙酰丙酮为原料反应制备配体，将小分子有机锂溶液与配体溶液混合，然后反应，得到脱质子β-酮亚胺锂化合物。本发明克服了现有技术都集中在单负离子β-酮亚胺为骨架的配合物的技术偏见，首次公开了双负离子β-酮亚胺基配合物，填补了现有技术空白。
