【摘要】 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 .更多还原

【Abstract】 This paper first reports the biomimetic catalytic character of new Schiff base mononuclear complexes MH₂L｛M = Mn（Ⅱ）, Fe（Ⅲ）Cl, Cr（Ⅲ）Cl, Cu（Ⅱ）, Co（Ⅱ）, Ni（Ⅱ）, Zn（Ⅱ）; L = bis[N,N-ethylene-2,2-（phenylmethylene）bis（3,4-dimethylpyrrole-5-aldimino）]｝ and dinuclear complexes MnML[M = Mn（Ⅱ）, Fe（Ⅲ）Cl, Cr（Ⅲ）Cl, Cu（Ⅱ）, Co（Ⅱ）, Ni（Ⅱ）, Zn（Ⅱ）] for the monooxygenation of cyclohexane with PhIO. The results showed that the catalytic property of the dinuclear complex is better than that of the mononuclear complex, so we supposed that there is some cooperation between the two metals in these dinuclear complexes. It seems that this cooperation increases with the increase of the number of unpaired d electrons in the dinuclear complexes.更多还原
