【摘要】 <正>A series of β-ketoimine ligands with varying fluorine substitution on the N-aryl ring and the corresponding copper complexes were synthesized.The fluoro-substituents exerted significant influences on the structure and catalytic activity of the copper complexes.^1-5X-ray Diffraction（XRD）revealed that the copper（II）central ion were coordinated by two trans-orientedβ-ketoimino ligands with delocalized double bonds.Complex 2b（with mono-o-fluoro-substitution on the N-aryl moiety）adopted a central symmetric square planar structure,while complex 2f(with bis-o-fluoro-更多还原
