5种取代四苯基氧代钼卟啉化合物的合成

以乙酸和丙酸为混合溶剂,硝基苯为氧化剂,合成了5种取代四苯基卟啉配体。再以十氢萘为溶剂,五氯化钼为金属盐反应合成了氧代钼卟啉化合物。经紫外-可见光谱和红外光谱对目标产物进行了结构表征。进一步考察了反应温度、五氯化钼金属盐用量和卟啉配体浓度对金属化产物的收率影响。金属化收率达到了86%～96%,采用两步法合成氧代钼卟啉的总收率达17.7%～44.4%。

Synthesis of five substituted oxo-molybdenum tetraphenyl-porphyrin compounds

Five substituted tetraphenylporphyrin compounds were prepared using nitrobenzene as an oxidant and mixed-solvent of acetic acid and propionic acid as the solvent.Then oxo-molybdenum substituted tetraphenylporphyrins were synthesized using molybdenum pentachloride as the metal salt in the solvent of decalin.The structures of these targeted products were confirmed by UV-Vis and IR.The effects of reaction temperature,metal salt dosages and concentration of porphyrin ligand toward the yields of metallation process were further investigated.The yields of metallation reached up to 86%~96%,and the total yields of substituted oxo-molybdenum tetraphenylporphyrin prepared using this two-step method were obtained from 17.7% to 44.4%.
