新型Salen-卟啉金属配合物催化剂的研究

Study of complexes of Salen-porphyrin

以5-对氨基苯基-10,15,20-三苯基卟啉和水杨醛为原料,合成水杨醛缩氨基四苯基卟啉,分别加入Ni(NO3).26H2O和Mn(OAc)2.4H2O,经络合反应,合成了两个同时具有卟啉结构和Salen结构的配合物3a和3b,产率分别为75%和80%,各化合物均通过UV-Vis,IR,1HNMR,元素分析进行表征。将配合物3a和3b应用于环己烷的催化氧化,环己烷的转化率分别达到了8.25%和12.45%。

5-（4-salicylidene amino phenyl） -10, 15,20-triphenyl-porphyrin were synthesized from 5-（4- amidophenyl） -10,15,20-triphenyl-porphyrin and salieylaldehyde. The Salen-porphyrin complexes 3 a and 3b were obtained after eomplexing with Ni （NO3 ）2·6H2O and Mn（OAe） 2·4H2O with the yields of 75% and 80% respectively. The structure of these compounds were characterized by the UV-Vis, IR,^1H NMR and elemental analysis. The complexes 3a and 3b were applied in reaction of catalytic oxidation of cyclohexane,the conversion of eyelohexane achieved 8.25% and 12.45% respectively.
