Patent ID: 8692010

Claim:
A method of synthesizing a copper bis-diketiminate compound having the formula of Compound (I) or a copper bis-ketoiminate compound having the formula of Compound (II): wherein each of R 1 to R 5 is independently selected from the group consisting of H, C1-C5 alkyl, alkyl amino, and SiR′ 3 , wherein R′ is a C1-C5 alkyl, the method comprising: Dissolving a copper halide in a first anhydrous solvent to produce a copper halide solution, mixing the copper halide solution with a solution of a sodium alkoxide in a second anhydrous solvent to produce a suspension, adding to the suspension a solution of a diketimine or a ketoimine in a third anhydrous solvent to produce a final mixture, and isolating the copper bis-diketiminate compound or the copper bis-ketoiminate compound from the final mixture.
