METHOD FOR PREPARING TRANSITION METAL COMPLEXES

摘要

PURPOSE: A method for preparing a novel transition metal compound is provided to simply prepare the transition metal compound and easily remove lithium chloride. CONSTITUTION: A method for preparing a transition metal compound comprises: a step of reacting alkyl lithium with amine-based compound of chemical formula 1; a step of adding a compound containing a protecting group to obtain a compound of chemical formula 2; a step of reacting alkyl lithium with the compound of chemical formula 2; a step of adding ketone-based comound of chemical formula 3 and lithium chloride to obtain a amine based compound of chemical formula 4; a step of reacting n-butyl lithium with /the compound of chemical formula 4 to obtain dilithium compound of chemical formula 5; a step of reacting organic lithium compound with the compound of chemical formula 5 to obtain the transition metal compound of chemical formula 6.
