两种三核配合物 N,N′—双(2—氨基苯甲酰基)乙二胺钯(Ⅱ)/铂(Ⅱ)(N,N′—bis(2—aminobenzovl)cthylenediaminc Pd(Ⅱ)/Pt(Ⅱ))已被合成.其配体 N,N′—双(2—氨基苯甲酰基)乙二胺(N,N′—bis(2—aminobenzoyl)cthylenediaminc,简称 abcaH_2)的合成机理初步被论证.反应物、吡啶及亚磷酸三苯酯三元中间体的形成可促使酰胺键的形成.经元素分析,IR、UV—Vis、~1HNMR、MS 及摩尔电导的测定.确定了配体及配合物的结构.结果发现三核配合物的生成仅需一步反应.力图一步合成过渡金属(M=Cu(Ⅱ)、Co(Ⅱ)、Ni(Ⅱ)、Mn(Ⅱ))的三核配合物尚未成功.三核配合物中分别与酰胺 N 和芳胺 N配位的金属表现出差异.
Two kinds of trinuclear complex N, N’-bis (2-aminobenzovl) cthylenediaminc Pd (Ⅱ) / Pt (Ⅱ)) has been synthesized. The synthesis mechanism of N, N’-bis (2-aminobenzoyl) cthylenediaminc (abcaH_2) The formation of the ternary intermediate of reactant, pyridine and triphenyl phosphite can promote the formation of amide bond.It was confirmed by elemental analysis, IR, UV-Vis, ~ 1HNMR, MS and molar conductance determination that the ligand The results showed that the formation of the trinuclear complex was only one-step reaction, trying to synthesize the trinuclear complex of transition metal (M = Cu (Ⅱ), Co (Ⅱ), Ni (Ⅱ) The complexes have not been successful yet.The trinuclear complexes showed differences in the coordination of amides N and arylamines N respectively.
