摘要：
An asymmetric &bgr;-ketoiminate ligand compound, represented by the following chemical formula (4): wherein, R1 is a linear or branched alkyl group containing 1 to 8 carbon atoms; R2 is a linear or branched alkyl group containing 2 to 9 carbon atoms, with the proviso that R2 contains more carbon atoms than R1; R′ is a linear or branched alkylene group containing 1 to 8 carbon atoms or a hydrocarbon containing 1 to 3 ethylene ether or propylene ether moieties, represented by —(CH2)nO— (n=2 or 3); R3 is a hydrogen atom or a linear or branched alkyl group containing 1 to 9 carbon atoms; and X is an oxygen atom or a sulfur atom.
