摘　　要：合成了在苯环２，５位带有不同取代基（ＣＨ３、ＣＨ３Ｏ、Ｃｌ、Ｂｒ或Ｈ）的６种聚四芳基锰卟啉ｐ－ＰｏｌｙＴ（２，５－２Ｒ）ＰＰＭｎＣｌ和ｍ－ＰｏｌｙＴＰＰＭｎＣｌ，考察了它们催化ＰｈＩＯ氧化环己烷的性能，结果表明：这些聚四芳基锰卟啉具有显著的抗氧化稳定性，带供电子基的聚合物催化速度较快。Six new para or meta polymeric tetra(2,5-substituted phenyl) manganese porphyrins(p-PolyT(2,5-2R)PPMnCl or m-Poly TPPMnCl,R=H,CH 3,CH 3O,Cl,Br) were synthsized,and their catalytic properties in the oxidation of cyclohexane with PhIO studied.Marked rendency of polymeric manganese porphyrins retard the oxidation was observed.The electron donatihg substituent in p-PolyT(2, 5-2R)PPMnCl increased the activity and selectivity of the catalyst.
