系统地研究了新型Schiff碱单核及双核配合物在拟酶催化PhIO单加氧化环己烷反应中的催化性能 .结果表明 ,双核配合物MnML{M =Mn(Ⅱ ) ,Fe(Ⅲ )Cl,Cr(Ⅲ )Cl,Cu(Ⅱ ) ,Co(Ⅱ ) ,Ni(Ⅱ ) ,Zn(Ⅱ ) ;L =双 [N ,N’ 亚乙基 2 ,2’ (苯亚甲基 )二 (3,4 二甲基吡咯 5 醛缩亚胺 ) ]}的催化活性比对应的单核配合物MnH2 L与MH2 L之混合物的催化活性高 .因此 ,我们认为在双核配合物中两金属离子间存在协同作用 ,并发现这种协同作用一般随双核配合物中成单d电子数增加而增大 .
The catalytic properties of the novel Schiff base mononuclear and binuclear complexes were systematically investigated in the pseudo-catalysis of PhIO mono-cyclohexene oxidation. The results showed that the binuclear complex MnML {M = Mn (Ⅱ), Fe (Ⅲ) Cl , Cr (Ⅲ) Cl, Cu (Ⅱ), Co (Ⅱ), Ni (Ⅱ) and Zn 3,4-dimethylpyrrole-5 aldimine)]} has a higher catalytic activity than the corresponding mononuclear complex MnH 2 L and MH 2 L. Therefore, we believe that in the binuclear complex between the two metal ions There is a synergistic effect and found that this synergy generally increases with the number of singlet d electrons in the binuclear complex.
