摘　　要：研究了新型 Schiff碱双锰及双铁配合物在模拟酶催化 Ph IO单加氧化环己烷反应及被 Ph IO氧化破坏反应中的结构效应 .结果表明 ,随着这些配合物的环内空腔逐渐增大 ,其抗氧化稳定性、催化活性及催化反应产率依次降低 .The structural effects on the catalytic properties and the stabilities of new Schiff base complexes M 2L{M=Mn(Ⅱ), Fe(Ⅲ)Cl; L=bis[N,N′ alkylene 2,2′ (phenylmethylene) bis(3,4 dimethylpyrrole 5 aldimino)]; alkylene=1,2 ethylene, 1,3 propylene, 1,4 butylene} for the monooxygenation of cyclohexane with PhIO were studied. The results show that the catalytic activities and the stabilities of these complexes decrease with the increase of the cavity within the molecule of these complexes. We have found that the structural effects in these catalysts on their catalytic properties and stabilities are obvious, and the catalyst with five membered chelating ring is the best in the complexes.
