纵轴配位固载金属卟啉催化的环己烷氧化反应

Catalysis of Axial Supported metalloporphyrins for Cyclohexane Hydroxylation

由简单方法合成了 PVC,CPVC和 Al2 O3纵轴固载的氧桥连金属卟啉 TPPM( ) OL (M=Fe,Mn;L =PVC,CPVC和 Al2 O3) ,并将它们用于温和条件下催化 Ph IO氧化环己烷的反应 .实验结果表明 ,与未固载金属卟啉 TPPM( ) Cl比较 ,纵轴固载金属卟啉 TPPM( ) OL具有催化效率高 ,对产物的选择性强和重复使用性能好等优点 .

PVC,CPVC and Al 2O 3 supported metalloporphyrins,TPPM(Ⅲ)OL (M=Fe,Mn;L=PVC ,CPVC and Al 2O 3 ) were synthesized by a simple method.The cyclohexane hydroxylation catalyzed by these supported metalloporphyrins were studied.The supported metalloporphyrins were found to be more effective catalysts for cyclohexane hydroxylation under moderate conditions than unsupported metalloporphyrins,TPPM(Ⅲ)Cl (M=Fe,Mn), and be able to be reused.
