摘　　要：α-蒎烯氧化时通常用到挥发性溶剂,不够环保。而采用新型氨基酸离子液体-纳米金属有机框架Fe-MOFs协同催化体系,可实现无溶剂条件下α-蒎烯的清洁、温和转化。研究结果表明:用均苯四甲酸根(PMA)作配体时制备的Fe-PMA-60纳米棒可与氨基酸离子液体[C_(4)mim]Cys构成协同催化体系,以TBHP为氧源,在无溶剂及60℃条件下反应10h,α-蒎烯转化率为99.8%,主产物马鞭草烯酮、马鞭草烯醇的总选择性为81.0%。Fe-PMA-60重复使用8次,催化结果没有显著的变化。In view of the shortcoming of using volatile solvents in usual oxidation processes,a novel cooperative system based on amino acid ionic liquid(AAIL)and nanoscale Fe-based metal-organic frameworks(Fe-MOFs)may render solvent-free,clean and mild transformation ofα-pinene.The results show that Fe-PMA-60 nanorods containing pyromellitate(PML)ligand can form a synergistic catalytic system in the presence of AAIL([C_(4)mim]Cys).With tert-butyl hydroperoxide as the oxygen source,99.8%conversion of substrate and 81.0%total selectivity for verbenone and verbenol can be obtained after 10 h reaction at 60℃under solvent-free conditions.Fe-PMA-60 can be reused for at least nine consecutive runs without an apparent degradation in catalytic activity.
